# Bin2Dec
**Tier:** 1-Beginner
Binary is the number system all digital computers are based on.
Therefore it's important for developers to understand binary, or base 2,
mathematics. The purpose of Bin2Dec is to provide practice and
understanding of how binary calculations.
Bin2Dec allows the user to enter strings of up to 8 binary digits, 0's
and 1's, in any sequence and then displays its decimal equivalent.
This challenge requires that the developer implementing it follow these
constraints:
- Arrays may not be used to contain the binary digits entered by the user
- Determining the decimal equivalent of a particular binary digit in the
sequence must be calculated using a single mathematical function, for
example the natural logarithm. It's up to you to figure out which function
to use.
## User Stories
- [ ] User can enter up to 8 binary digits in one input field
- [ ] User must be notified if anything other than a 0 or 1 was entered
- [ ] User views the results in a single output field containing the decimal (base 10) equivalent of the binary number that was entered
## Bonus features
- [ ] User can enter a variable number of binary digits

# Calculator
**Tier:** 1-Beginner
Calculators are not only one of the most useful tools available, but they are
also a great way to understand UI and event processing in an application. In
this problem you will create a calculator that supports basic arithmetic
calculations on integers.
The styling is up to you so use your imagination and get creative! You might
also find it worth your time to experiment with the calculator app on your
mobile device to better understand basic functionality and edge cases.

# CauseEffect
**Tier:** 1-Beginner
Patterns are integral to software engineering and represent potentially
reusable components in program logic. However, patterns aren't used only
for program logic, they are exist in other domains such as DevOps, user
support, and the user interface.
A common user interface pattern is to summarize data in one section of a page
that consists of some type of list (like text, images, or icons) that describes
or categorizes a set of data. When a list item is clicked, the detailed data
behind it is displayed in an adjacent pane on the page.
For example, on a real estate site clicking an address in a list of properties
for sale displays the details about the property in another part of the
page.
This challenge requires that the developer implementing it follow these
constraints:
- You are responsible for creating your own test data. Use a hardcoded
Javascript object to define your test data (see below).
- Use only native HTML/CSS/Javascript in your first version of this app
- You may use other packages or libraries when implementing subsequent
versions.
## User Stories
- [ ] User can see a list of person names arranged vertically in a summary
pane on the page.
- [ ] User can click on a name in the list to update an adjacent pane on the
page with that individuals full name, address, telephone number, and
birthday.
- [ ] User can click on another name in the list to refresh the detail pane
with that individuals information.
## Bonus features
- [ ] User can see the person name in the summary pane highlighted when the
cursor is hovered over it.
- [ ] User can see the person name in the summary pane highlighted
using a selection effect (color, size, etc.) when it is clicked. This is a
different effect from the hover effect
- [ ] User can see the selection effect removed from a name in the summary
list when a new name is clicked.
## Useful links and resources
- [DOM Events](https://developer.mozilla.org/en-US/docs/Web/API/Event)
- Consider defining your test data in a JavaScript object having a format
such as this:
```
const people = [
{name: "...", street: "...", city: "...", state: "...", country: "...", telephone: "...", birthday: "..."},
.
.
.
{name: "...", street: "...", city: "...", state: "...", country: "...", telephone: "...", birthday: "..."}
];
```

================================================
# Christmas Lights
**Tier:** 1-Beginner
The ChristmasLights application relies on your development talents to create
a mesmerizing light display. Your task is to draw seven colored circles
in a row and based on a timer change the intensity of each circle. When
a circle is brightened it's predecessor returns to its normal intensity.
This simulates the effect of a string of rippling lights, similar to the ones
displayed during the Christmas Holidays.
## User Stories
- [ ] User can press a button to start and stop the display
- [ ] User can change the interval of time controlling the change in intensity
## Bonus features
- [ ] User can select the color used to fill each circle
- [ ] User can specify the intensity value
- [ ] User can change the size of any circle in the row
- [ ] User can specify the number of rows to be included in the display. From
one to seven rows can be chosen

================================================
# ColorCycle
**Tier:** 1-Beginner
The use of color plays a major role in an applications User Interface and
User Experience (UI/UX). ColorCycle seeks to help WebDev's better understand
RBG colors by making small changes to a colored box over time.
This app draws a box filled with a user specified color and makes small changes
over time also based on user input. In other words, from cycles through
changes to the originally specified color. These changes allow the user to
experience the visual impact different changes to the individual parts of
an RGB color specification (e.g. `#000000` color code).
## User Stories
- [ ] User can specify a starting fill color as a six hexadecimal standard
CSS color code in three individual components of two digits each - red,
blue, and green
- [ ] User can specify an increment value for each color component that will
be added to that component every .25 second
- [ ] User can see the box containing the fill color change every .25 seconds
- [ ] User can only change the color components and their increments when
the app is stopped
- [ ] User can start and stop the fill operation using a button whose name
changes to 'Start' when stopped and 'Stop' when started
- [ ] User will receive an warning if something other than hexadecimal digits
are entered for the color components
## Bonus features
- [ ] User can change the time interval between color changes
- [ ] User can specify the color encoding format used from RGB to another format like HSL

# Countdown Timer
**Tier:** 1-Beginner
We all have important events we look forward to in life, birthdays,
anniversaries, and holidays to name a few. Wouldn't it be nice to have an app
that counts down the months, days, hours, minutes, and seconds to an event?
Countdown Timer is just that app!
The objective of Countdown Timer is to provide a continuously decrementing
display of the he months, days, hours, minutes, and seconds to a user entered
event.
### Constraints
- Use only builtin language functions for your calculations rather than relying
on a library or package like [MomentJS](https://momentjs.com/). This assumes,
of course, that the language of your choice has adequate date and time
manipulation functions built in.
- You may not use any code generators such as the
[Counting Down To](https://countingdownto.com/) site. You should develop your
own original implementation.
## User Stories
- [ ] User can see an event input box containing an event name field, an
date field, an optional time, and a 'Start' button.
- [ ] User can define the event by entering its name, the date it is
scheduled to take place, and an optional time of the event. If the time is
omitted it is assumed to be at Midnight on the event date in the local time
zone.
- [ ] User can see a warning message if the event name is blank.
- [ ] User can see a warning message if the event date or time are incorrectly
entered.
- [ ] User can see a warning message if the time until the event data and time
that has been entered would overflow the precision of the countdown timer.
- [ ] User can click on the 'Start' button to see the countdown timer start
displaying the days, hours, minutes, and seconds until the event takes place.
- [ ] User can see the elements in the countdown timer automatically
decrement. For example, when the remaining seconds count reaches 0 the remaining
minutes count will decrement by 1 and the seconds will start to countdown from 59. This progression must take place from seconds all the way up to the remaining days position in countdown display.
## Bonus features
- [ ] User can save the event so that it persists across sessions
- [ ] User can see an alert when the event is reached
- [ ] User can specify more than one event.
- [ ] User can see a countdown timers for each event that has been defined.

# Dollars To Cents
**Tier:** 1-Beginner
Converting dollars to cents would enable you to practice your fundamental knowledge of programming. Loops, if conditions and a simple algorithm will be used.
Your task is to let the user input a dollar value (float), assuming that it can also accept extra cents (ex. $2.75), and convert it into an integer (in this case, if $2.75 = 275). After this, convert into coins with the sub-type of dollars: penny, nickel, dime and quarter. Use an algorithm that would divide the dollar value to the four coin types, and output few coins as possible.
The challenge: Try this without using any frameworks.
(EX. If you have $0.58, I would have 4 coins: 2 quarters, 0 dimes, 1 nickel and 3 pennies)
## User Stories
- [ ] User can enter a dollar value
- [ ] User can see the total cents from the converted dollar value
## Bonus features
- [ ] User can see how many were pennies, nickels, quarters and dimes from the total cents

# Dynamic CSS Variables
**Tier:** 1-Beginner
CSS variables are a powerful tool that lets the developer associate a symbolic
name with a value, and then use that name in the stylesheet wherever that
value is required. The advantage is that when a change to that value is
required it only needs to change in the CSS variable definition rather than in
the many spots it may be used.
What can make this even more powerful is to dynamically change the value of a
CSS variable at runtime.
The goal of this app is to dynamically change the background color of text boxes
based to let you gain experience using both CSS variables and dynamically
changing them from within the app.
## User Stories
- [ ] User can see three two boxes to be used to enter a User ID and Password
along with 'Cancel' and 'Login' buttons underneath them. The default background
color of the text boxes is white.
- [ ] User can enter a user id and password into the text boxes.
- [ ] User can click the 'Login' button to validate the user id and password.
- [ ] User can see a warning message if one or both of the text boxes contains
spaces and the background color of the empty text box will change to light
yellow.
- [ ] User can see a warning message if the user id doesn't match 'testuser'
and the background color of the text box will change to light red.
- [ ] User can see a warning message if the password doesn't match 'mypassword'
and the background color of the text box will change to light red.
- [ ] User can click the 'Cancel' button to clear the text boxes and reset
their background colors to white.
## Bonus features
- [ ] User can see the color of the text box border change when an error is
detected
- [ ] User can see the size and font of the contents of the text box change
when an error is detected.

================================================
# Your First DB App
**Tier:** 1-Beginner
Understanding database concepts and how to use them in your applications is
knowledge all developers need to acquire. The objective of Your First DB App
is to provide a gentle introduction to database concepts and learning one
use case for databases in a frontend app.
So, did you know that modern browsers have a database management system
built into them? IndexedDB is built into most modern browsers and provides
developers with basic database features, transaction support, and client-side
cross-session persistance.
### Requirements & Constraints
- The primary use case for a browser based database is to maintain state or
status information that needs to persist across sessions, or as a work area
for temporary data. For example, data retrieved from a server that must be
reformatted or cleansed before it's presented to the user.
- It is important to keep in mind that since the client-side browser
environment cannot be secured you should not maintain any confidential or
personal identifying information (PII) in a browser based database.
- The following Javascript class is provided with the functionality to allow
your app to initially populate and clear the database from the browser so you
can test the query logic you'll be adding. You'll be required to hook up
buttons on the web page you build to the `clearDB` and `loadDB` functions, and
to write your own `queryDB` handler to connect to the `Query DB` button. You'll
also need to add a `queryAllRows` function to the Customer class.
```js
class Customer {
constructor(dbName) {
this.dbName = dbName;
if (!window.indexedDB) {
window.alert("Your browser doesn't support a stable version of IndexedDB. \
Such and such feature will not be available.");
}
}
/**
* Remove all rows from the database
* @memberof Customer
*/
removeAllRows = () => {
const request = indexedDB.open(this.dbName, 1);
request.onerror = (event) => {
console.log('removeAllRows - Database error: ', event.target.error.code,
" - ", event.target.error.message);
};
request.onsuccess = (event) => {
console.log('Deleting all customers...');
const db = event.target.result;
const txn = db.transaction('customers', 'readwrite');
txn.onerror = (event) => {
console.log('removeAllRows - Txn error: ', event.target.error.code,
" - ", event.target.error.message);
};
txn.oncomplete = (event) => {
console.log('All rows removed!');
};
const objectStore = txn.objectStore('customers');
const getAllKeysRequest = objectStore.getAllKeys();
getAllKeysRequest.onsuccess = (event) => {
getAllKeysRequest.result.forEach(key => {
objectStore.delete(key);
});
}
}
}
/**
* Populate the Customer database with an initial set of customer data
* @param {[object]} customerData Data to add
* @memberof Customer
*/
initialLoad = (customerData) => {
const request = indexedDB.open(this.dbName, 1);
request.onerror = (event) => {
console.log('initialLoad - Database error: ', event.target.error.code,
" - ", event.target.error.message);
};
request.onupgradeneeded = (event) => {
console.log('Populating customers...');
const db = event.target.result;
const objectStore = db.createObjectStore('customers', { keyPath: 'userid' });
objectStore.onerror = (event) => {
console.log('initialLoad - objectStore error: ', event.target.error.code,
" - ", event.target.error.message);
};
// Create an index to search customers by name and email
objectStore.createIndex('name', 'name', { unique: false });
objectStore.createIndex('email', 'email', { unique: true });
// Populate the database with the initial set of rows
customerData.forEach(function(customer) {
objectStore.put(customer);
});
db.close();
};
}
}
// Web page event handlers
const DBNAME = 'customer_db';
/**
* Clear all customer data from the database
*/
const clearDB = () => {
console.log('Delete all rows from the Customers database');
let customer = new Customer(DBNAME);
customer.removeAllRows();
}
/**
* Add customer data to the database
*/
const loadDB = () => {
console.log('Load the Customers database');
// Customers to add to initially populate the database with
const customerData = [
{ userid: '444', name: 'Bill', email: 'bill@company.com' },
{ userid: '555', name: 'Donna', email: 'donna@home.org' }
];
let customer = new Customer(DBNAME);
customer.initialLoad(customerData);
}
```

# FlipImage
**Tier:** 1-Beginner
It's important for Web Developers to understand the basics of manipulating
images since rich web applications rely on images to add value to the user
interface and user experience (UI/UX).
FlipImage explores one aspect of image manipulation - image rotation. This
app displays a square pane containing a single image presented in a 2x2
matrix. Using a set of up, down, left, and right arrows adjacent to each
of the images the user may flip them vertically or horizontally.
You must only use native HTML, CSS, and Javascript to implement this app.
Image packages and libraries are not allowed.
## User Stories
- [ ] User can see a pane containing a single image repeated in a 2x2 matrix
- [ ] User can flip any one of the images vertically or horizontally using a set of up, down, left, and right arrows next to the image
## Bonus features

# GitHub Status
**Tier:** 1-Beginner
Web apps acquire data in many ways. Through user input in web pages, through
API's to backend systems, from files and databases, and sometimes by "scraping"
websites. The objective of the GitHub Status app is to introduce you to one
way to scrape information from another web site.
GitHub Status uses the NPM Request package to retrieve the current GitHub site
status from the [GitHub Status](https://www.githubstatus.com/) web site. The
Request package allows websites to be retrieved not to a browser window, but
as a JSON document that can be readily accessed by your code.
Although this application specification relies heavily on Javascript, feel free
to develop it using your language of choice!
## User Stories
- [ ] User can see the current status for GitHub Git operations, API Requests,
Operational Issues, PRs, Dashboard, & Projects, Operational Notifications,
Operational Gists, and Operational GitHub Pages as a list in the main app
window.
- [ ] User can retrieve the most recent status from the GitHub Status web
site by clicking a 'Get Status' button.
## Bonus features
- [ ] User can see any of the GitHub components that are not in 'Operational'
status highlighted by a different color, background animation, or any other
technique to make it stand out. Use your imagination!

web site page from the command line command `node ghstatus`. You can use this
output to determine which JSON element contain the status information you'll
need to develop this app.
```

# Hello
**Tier:** 1-Beginner
It is a given that applications must provide users with the functionality
necessary to accomplish some task or goal. The effectiveness of app functionality
is the first determinate of how users perceive the apps they use. However, it
is not the only thing that influences user satisfaction.
The User Interface and User Experience (UI/UX) features developers build into
apps have at least an equal amount of influence on users perception of an app.
It may be an oversimplification, but UI/UX is largely (but not wholly)
concerned with an apps "form". Personalization is an aspect of UX that tailors
characteristics and actions to
the individual user. Personalizing app functionality in this manner works to
make the app easier and more pleasing to use.
The objective of the Hello app is to leverage geolocation to obtain the users
country so it can then generate a customized greeting in the users native
language.
### Constraints
- Developers should use the [IP-API](http://ip-api.com/docs/api:json) service
to obtain the users IP.
- Developers should use the
[Fourtonfish](https://www.fourtonfish.com/hellosalut/hello/) service to
obtain the greeting in the users native language by passing the users IP.
- Developers must use a HTML entities decoding to decode the hello message.
## User Stories
- [ ] User can see a mock login panel containing a user name text input field,
a password text input field, and 'Login' and 'Logout' buttons.
- [ ] User can enter a mock login name into the User Name field.
- [ ] User can enter a mock password into the Password field. Input should
be masked so the user see's asterisks (`*`) for each character that is entered
rather than the plaintext password.
- [ ] User can click the 'Login' button to perform a mock login.
- [ ] User can see a message if either or both of the input fields are empty
and the border color of the field(s) in error should be changed to red.
- [ ] User can see a login acknowledgement message in the format:
`<hello-in-native-language> <user-name> you have successfully logged in!`
- [ ] User can click the 'Logout' button to clear the text input fields and
any previous messages.
- [ ] User can see a new message when successfully logged out in the format:
`Have a great day <user-name>!`
## Bonus features
- [ ] User can see an additional text input field for a language code which
will be used to override the IP obtained through geolocation. Hint:
this is a great feature for testing your app.
- [ ] User can see additional geolocation information after logging on that
includes at least the local IP address, city, region, country name, zip code,
longitude, latitude, and timezone.

# IOT Mailbox Simulator
**Tier:** 1-Beginner
The objective of the IOT Mailbox Simulator is to mimic how an Internet of Things
(IOT) enabled physical mailbox might be used to notify you when "snail" mail
has arrived. In doing so it will provide you with experience using callbacks
to communicate state between different components of an app that are dependent
on one another.
### Requirements & Constraints
- Even though this app is specified using Javascript concepts and terminology
you are free to implement it in the language of your choice.
- The following Javascript class is provided to start and stop the monitoring
process, and to signal the app web page with the state of the mailbox door
(open or closed) at preset intervals. Keep in mind that the interval you specify
shouldn't exceed the time it normally takes to open or close the door or you
might miss a delivery!
```
/**
* Monitor the light levels inside an IOT enabled snail mailbox to detect
* when the mailbox door has been opened and closed.
* @class IOTMailbox
*/
class IOTMailbox {
/**
* Creates an instance of IOTMailbox.
* @param {number} [signalInterval=500] Timer interval for checking mailbox status.
* @param {function} signalCallback Function to invoke when the timer interval expires.
* @memberof IOTMailbox
*/
constructor(signalInterval = 500, signalCallback) {
this.signalInterval = signalInterval;
this.signalCallback = signalCallback;
this.intervalID = null;
this.lastLightLevel = 0;
}
/**
* Start monitoring of the mailbox and invoke the caller specified callback
* function when the interval expires.
* @memberof IOTMailbox
*/
startMonitoring = () => {
console.log(`Starting monitoring of mailbox...`);
this.intervalID = window.setInterval(this.signalStateChange, this.signalInterval);
}
/**
* Stop monitoring the mailbox status
* @memberof IOTMailbox
*/
stopMonitoring = () => {
if (this.intervalID === null) return;
window.clearInterval(this.intervalID);
this.intervalID = null;
console.log(`Mailbox monitoring stopped...`);
}
/**
* Pass the current light level inside the mailbox to the users callback
* function. The positive light levels indicate the door is open while
* negative levels indicate it is closed. Depending on the sampling interval
* the mailbox door could be in any postion from fully closed to fully open.
* This means the light level varies from interval-to-interval.
* @memberof IOTMailbox
*/
signalStateChange = () => {
const lightLevel = this.lastLightLevel >= 0
? Math.random().toFixed(2) * -1
: Math.random().toFixed(2);
console.log(`Mailbox state changed - lightLevel: ${lightLevel}`);
this.signalCallback(this.lightLevel);
this.lastLightLevel = lightLevel;
}
};
```
## User Stories
- [ ] User can see a web page containing a control panel containing three
buttons - 'Start Monitoring', 'Stop Monitoring', and 'Reset'.
- [ ] User can see a notification panel where the mailbox status will be posted.
- [ ] User can see a scrollable log panel where execution details describing
the apps operation and interface with the IOTMailbox instance will be posted.

# JSON2CSV
**Tier:** 1-Beginner
Developers and end users are both experts in their own domains and as such,
each speaks using a domain-specific language and terminology. This also extends
to the tools used to manipulate data. Developers have found JSON to be a
universally accepted method for transferring data between applications. End
Users, on the other hand, rely on spreadsheets to organize and analyze data.
The objective of JSON2CSV is to help bridge the gap between JSON and CSV by
converting JSON to CSV to make it easier to review data in a spreadsheet. It
allows the user to paste JSON into a text box to generate its equivalent CSV.
### Constraints ###
- You may not use any libraries or packages designed to perform this type of
conversion.
- If you choose to implement this in JavaScript don't use complicated looping
in your first implementation. Instead, use `Object.keys()` and `Object.values`
to generate CSV for the header and data rows.
- Nested JSON structures are not supported.
## User Stories
- [ ] User can paste JSON syntax into a text box
- [ ] User can click a 'Convert' button to validate the JSON text box and convert it to CSV
- [ ] User can see the converted CSV in another text box
- [ ] User can see an warning message if the JSON text box is empty or if it doesn't contain valid JSON
- [ ] User can click a 'Clear' button to clear the contents of both the JSON and CSV text boxes.
## Bonus features
- [ ] User can enter the path to the JSON file on the local file system in a text box
- [ ] User can click a 'Open' button to load file containing the JSON into the text box
- [ ] User can see a warning message if the JSON file is not found
- [ ] User can enter the path the CSV file is to be saved to in a text box
- [ ] User can click a 'Save' button to save the CSV file to the local file system
- [ ] User can see a warning message if the CSV text box is empty or if the save operation failed.
- [ ] User can convert CSV data to JSON. See [CSV2JSON](./CSV2JSON-App.md)

# Javascript Validation With Regex
**Tier:** 1-Beginner
In this challenge, you'd create a javascript validation script to validate the inputs entered by a user using RegEx.
You could always refer to the [Regular Expression Library](http://regexlib.com/(X(1)A(GijS7qxVy-6Gyc4cweUyFoK4ZvRn2WnlOe8SSKuq9sT7ps-2nbiTmZZMTCn_rFk4-mNoGnYL-DPU8pJhmNNOtkP-syqWE4WO_1aVt4bPa5nTsQPQe6VRAALnm6QW3YIWbYkVS78JFbZN39vmMI1UYiWlHXKwNMB99WjsZOn0qc_8dcN0unp2KMOBw0P__3OH0))/CheatSheet.aspx?AspxAutoDetectCookieSupport=1) for support
For this project, there'd be three required inputs for validation:
- The first would require the user to enter five (5) capital letters, six (6) symbols and two hyphens (-) in any order. This could be used as a password.
- The second which could be used as username would require the user to enter letters without spaces
- The third which could be used as email address would require the user to enter only email addresses on gmail (...@gmail.com).
## User Stories
- [ ] User should be notified of any invalid inputs by error messages displayed on the form.
- [ ] The submit button on the form would never be executed until all entries are validated.

# Key Value
**Tier:** 1-Beginner
Have you ever thought about what it means that the computer you are using is
a digital device? Among other things it means that everything its capable of
is achieved by translating a digital signal into a sequence of binary digits - 0's and 1's. These binary digits form codes used to represent data.
The keyboard you used to retrieve this project description is a great example
of this. Pressing a key generates a digital signal that is translated by the
computer into a code representing the key that was pressed.
The goal of the Key Value app is to display the encoded value on screen each
time a key is pressed on the keyboard.
## User Stories
- [ ] User can see a display panel containing a text area where the key value
and key code will be displayed along with display areas for four other
indicators related to the keys on the keyboard - alt key, control key,
meta key, and shift key.
- [ ] User can see the key code and key value displayed in the display panel

# Pearson Regression
**Tier:** 1-Beginner
There are few, if any, applications that don't require some form of
cross-disciplinary knowledge in order to implement useful functionality for
a user. In the case of an app for the medical profession it might be domain
expertise in biology or pharmacology. A paint manufacturer or a crop science
business might rely on apps with an intimate knowledge of chemistry. And, a
payroll application will certainly incorporate HR and accounting concepts.
Regardless of the industry segment an app is developed for one cross domain
expertise in common with them all is mathematics. As an application developer
you don't have to be a mathematician, but it's useful to have an understanding
of how to apply mathematical concepts to the problems you are trying to solve.
The objective of this app is to apply the Pearson Correlation Coefficient
against two sets of data to provide the user with the degree to which they
may or may not be related. For example, given a set of temperatures and another
set of car prices this would let the user test whether or not they are related
(spoiler alert: they are unrelated!).
### Constraints
- The Developer must program all calculations without relying on a package.
## User Stories
- [ ] User can see an input panel with two input fields allowing entry of `x`
and `y` coordinates, and 'Add' and 'Calculate' buttons.
- [ ] User can enter numbers into these boxes where `x` and `y` are observations
from the two data sets.
- [ ] User can click the 'Add' button to add the `x` and `y` to a tabular
output area listing the pairs of observations.
- [ ] User can see and error message if either of the two input fields are
empty or do not contain valid real numbers.
- [ ] User can see the 'Calculate' button is disabled until errors have been
corrected.
- [ ] User can click the 'Calculate' button to perform the regression analysis
and to display its results.
- [ ] User can see results of the calculation which include:
- Arithmetic means for both the `x` and `y` observations
- Standard deviations for both the `x` and `y` observations
- Pearson correlation coefficient with one of the following interpretations:
- No correlation
- Neutral
- Some correlation
## Bonus features
- [ ] User can see a scatter plot of the observations
- [ ] User can upload observations from a file on the local machine.
- [ ] User can see a regression line overlaying the scatter plot

# TrueOrFalse
**Tier:** 1-Beginner
Something every developer needs to clearly understand is the result of
conditional expressions like `x === y`. This is a bit more involved for
Javascript developers who must also understand the concept of _truthiness_.
TrueOrFalse helps by displaying the result when a conditional operator is
applied to two values. Users can use this to test their knowledge and
explore edge cases.
The two values and the conditional operator are entered by the user and the
result to be displayed will be TRUE or FALSE. The implementation must not use
the `eval()` function to generate the result of the conditional.
## User Stories
- [ ] User can enter two strings to be compared
- [ ] User can enter a valid Javascript conditional operator to be used to compare the two strings
- [ ] User can see the result of the conditional as TRUE or FALSE
- [ ] User can see a warning if the input strings or conditional operator that has been entered is not valid
## Bonus features
- [ ] User can specify the type of each of the two strings so numbers can be compared to strings, strings to booleans, etc

# Typing Speed Test App
**Tier:** 1-Beginner
Typing speed tests are a fun and interactive way to measure how fast and accurately you can type.
In this project, you'll build a simple **Typing Speed Test App** that displays a random passage for the user to type within a limited time.
Once the timer runs out (or the user finishes typing), the app calculates and displays their **typing speed (WPM)** and **accuracy (%).**
This project will help you understand **real-time input handling**, **timing events**, and **DOM manipulation** — essential skills for building interactive web apps.
## Features
- **Real-time Timer** – Start typing to begin the timer automatically.
- **Live Accuracy Check** – Incorrect letters are highlighted instantly.
- **Performance Stats** – Get detailed results including Words Per Minute (WPM) and Accuracy (%).
- **Restart Option** – Take the test again with a new random passage.
- **No External Libraries** – All calculations implemented manually.
## User Stories
- [ ] User can see a **random passage** to type on the screen.
- [ ] User can start the test by clicking a **Start** button (starts the timer).
- [ ] User can see a **typing input area** to type the given text.
- [ ] User can view a **countdown timer** showing how much time is left (e.g., 60 seconds).
- [ ] User can see their **WPM** and **Accuracy (%)** after finishing or when the timer ends.
- [ ] User can click **Restart** to take the test again with a new passage.
- [ ] User sees **real-time error highlighting** while typing.
## Bonus Features
- [ ] User can select different **time durations** (15s, 30s, 60s, 120s).
- [ ] User can choose **difficulty levels** or text lengths.
- [ ] User’s **best WPM** is saved locally using `localStorage`.
- [ ] **Dark/Light Mode** toggle for better UI experience.
- [ ] Live **WPM and Accuracy** tracking while typing.
- [ ] **Progress Graphs or History** showing previous scores.
## Constraints
- Do not use any third-party libraries for typing speed or accuracy calculations.
- Use only front-end technologies like **HTML**, **CSS**, and **JavaScript** (or React if preferred).
## How to Calculate WPM
**Words Per Minute (WPM)** = (Total Characters Typed / 5) ÷ (Time in Minutes)
**Accuracy (%)** = (Correct Characters / Total Characters Typed) × 100

# Vigenere Cipher
**Tier:** 1-Beginner
The rate and impact of security breaches in recent years makes it imperative
that developers understand the methods bad actors use to compromise apps.
Understanding how an app can be compromised is the first step in coming up
with effective protection measures.
One of the easiest ways bad actors can compromise an app is to access
data that's left unencrypted by the developer. There are a number of strong
encryption algorithms available to ensure that data is not readable even if
access is compromised. These include AES, Blowfish, and TripleDES to name a
few.
However, these algorithms can be quite complex to implement so the objective
of this app is to implement a classical encryption algorithm, the Vigenere
Cipher to learn the basics of how ciphers work.
### Requirements & Constraints
- Developers should use only native language features to implement the Vigenere
Cipher. Libraries are not allowed.
- Developers should design and implement their own solution using only the
description of the steps in the Vigenere Cipher algorithm.
- After successfully implementing this algorithm Developer should ask
themselves these questions:
- Would you feel confident encrypting your financial information using the
Vigenere Cipher? Why?
- How would you detect that a message had been encrypted using the
Vigenere Cipher?
- How would you go about trying to crack this encryption?
## User Stories
- [ ] User can see the app window with these components:
- Plain text message input field
- Encryption key input field
- Action buttons - 'Encrypt' and 'Decrypt'
- Resulting encrypted or decrypted message
- [ ] User can enter the text to be encrypted in the plain text message input
field
- [ ] User can enter the Encryption key the Vigenere algorithm will use to
encrypt the plain text message.
- [ ] User can click see see the 'Decrypt' button disabled until the plain
text has been encrypted.
- [ ] User can click the 'Encrypt' button to encrypt the plain text message
- [ ] User can see the encrypted message displayed in the result field.
- [ ] User can see the 'Decrypt' button enabled after the encrypted message
has been displayed.
- [ ] User can click the 'Decrypt' button to decrypt the encrypted message
and to display its contents in the result field.
## Bonus features
- [ ] User can see a 'Compare' button after decryption that compares the
original plain text message with the decrypted message
- [ ] User can see an error message if the 'Compare' detects differences
in the contents of these two fields.

/* do something */
}
```
If and switch statements work well for a limited number of conditionals, but
what if your app had 10's or 100's of conditionals to evaluate? Luckily, there's
another way.
The goal of the Bit Masks app is demonstrate how to use bit masks to evaluate
longer sequences of switches without having to rely on long strings of
conditional statements.
## User Stories
- [ ] User can see a vertical list of checkboxes with the following cities
and their timezones:
- Moscow: GMT +3
- Paris: GMT +2
- Berlin: GMT +2
- Brussels: GMT +2
- Amsterdam: GMT +2
- Rome: GMT +2
- London: GMT +1
- Dublin: GMT +1
- New York: GMT -4
- Washington, DC: GMT -4
- St. Louis: GMT -5
- Los Angeles: GMT -7
- Tokyo: GMT +9
- Beijing: GMT +8
- Ho Chi Mihn City: GMT +7
- Mumbai: GMT +5
- [ ] User can see a GMT search box where an integer representing a GMT offset
can be entered into and a 'Find Cities' button.
- [ ] User can click the 'Find Cities' button to display the names of the
cities in that GMT offset in an output area.
### Developer Notes
For this exercise the developer should use sequences of 24
binary bits, each corresponding a GMT time zone from +12 to -12 to map cities
to their timezones.
Searches should be conducted by combining a bit mask for the desired time zone
against the city-specific bit sequences to identify matches. Determining if a
city meets the search criteria shouldn't rely on a statement such as
```
if (city[i].gmtOffset === searchOffset ) {
/* Found it! */
}
```
It should instead rely on a bitwise operation.
## Bonus features
- [ ] User can search for cities NOT in the GMT offset entered in the
search box.
- [ ] User can see a summary count of the number of cities that met the
search criteria.

================================================
# Charity Finder
**Tier:** 2-Intermediate
With the Charity Finder app you'll not only get to refine your Web Developer
skills, but you will also have an opportunity to see how you can do good. The
objective of this app is to utilize the [Global Giving](https://www.globalgiving.org/) organizations API to provide your users with a list of global charities they
can search to find a charity that matches their philanthropic interests.
### Constraints
- Since the app is asking the user to choose and contribute to a charitable
cause it's important that the presentation of information be clear and concise.
Just as important is the need for the UI/UX to be polished and engaging to use.
Although this is true of all apps, its even more the case here since each
user that abandons the site represents the loss of an opportunity to do good
(see ['What is Web Site Conversion?](##useful-links-and-resources)) below.
## User Stories
- [ ] User can see a page heading containing the application name.
- [ ] User can see an overview of what the app is intended for in 'splash'
page format.
- [ ] User can see a search area containing an set of drop down boxes that
allow the user to specify search criteria for charitable organizations
including:
- Organization name
- Organizations home country
- Countries the organization serves
- [ ] User can see a 'Search' button
- [ ] User can click on the 'Search' button to display information cards
for the matching organizations in a search results area.
- [ ] User can see organization information cards in the search results area
containing:
- ID
- Name
- Address
- Logo
- [ ] User can click the logo in the organizations information card to open a
new window to that organizations home page.
- [ ] User can see a page footer with links to your GitHub and social media
accounts including social media icons (like the Twitter icon).
## Bonus features
- [ ] User can see a search dropdown for themes the charity focuses on.
- [ ] User can select multiple options in the search dropdowns.
- [ ] User can see a project link (e.g. 'PROJECT') on the organization
information card.
- [ ] User can click on the project link to display a page with information
describing the Global Giving project the organization is associated with.
Hint: examine the structure of the JSON returned from the API to understand
the relationship between projects and organizations.

# Flip Art
**Tier:** 2-Intermediate
Many developers have found that adding animation to an application is a
useful technique that adds impact to the UI, to make it more appealing to its users,
and to explain complex subject matter. But, as a developer how do you create
these and how do you know what images make effective animations?
The objective of the Flip Art app is to address both of these needs by
providing a simple way to collect and arrange a set of images into an
animated sequence that can be replayed and adjusted to achieve the desired
impact and effect.

# HighStriker
**Tier:** 2-Intermediate
Carnivals and circuses have featured the HighStriker sideshow game since at
least the 1930's. This game consists of a tower with a bell mounted at the top
and a levered platform at the bottom. When the levered platform is struck with
a mallet it causes a puck to travel up a track attached to the tower.
When the platform is struck the puck travels vertically up the track. If hit
hard enough the puck will ring the bell, signifying a winner.
The objective of the Highstriker app is to simulate this carnival
game. Instead of physical force to move the puck up the track use an algorithm
of your own design and a random number generator to determine the puck's
speed and the distance it travels.
## User Stories
- [ ] User can see an image of the High Striker tower with the bell at the
top, the levered platform at the bottom and the track connecting the two.
- [ ] User can click the 'Strike!' button under the levered platform to play
the game.
- [ ] User can see the puck travel up the rail.
- [ ] User can hear the bell ring if the puck travels far enough to strike it.
- [ ] User can see a score updated for each click of the 'Strike!' button -
the number of times the bell was struck and the number of attempts.
- [ ] User can click a 'Clear' button to clear the score.

# Podcast Directory
**Tier:** 2-Intermediate
In the [GitHub Status](../1-Beginner/GitHub-Status-App.md) app you learned how to use the
Request package to scrape information from a web page. The Podcast Directory
continues this process and introduces you to another web scraping package -
[Puppeteer](https://github.com/GoogleChrome/puppeteer).
Although Request is a useful package it isn't built specifically for web
scraping like Puppeteer. As you gain experience with web scraping you'll find
that there are web sites and applications where web scraping is made easier
by using a tool like Puppeteer that is specifically built for scaping.
It is important to note that while web scraping has its place, the use of
an API or a data source such as a file or database is always preferable to
scraping information from a page. The reason being that even minor changes to
page styling can render your web scraper inoperable. For example, the change
of a CSS class name your scraping logic is dependent on.
The goal of the Podcast Directory app is to pull the most recent episodes of
the [Javascript Jabber](https://www.podbean.com/podcast-detail/d4un8-57595/JavaScript-Jabber-Podcast)
and [Techpoint Charlie](https://www.podbean.com/podcast-detail/k76vd-8adc7/Techpoint-Charlie-Podcast)
podcasts from [Podbean](https://www.podbean.com) and create a new page that
creates a combined list of episodes, sorted by broadcast date.
## User Stories
- [ ] User can see a table of podcast episodes
- [ ] User can see rows in this table showing a clickable episode icon, the
title of the episode, and the date it was originally broadcast.
- [ ] User can scroll through the list
- [ ] User can click on the episode icon to display that episodes page on
the Podbean web site.
## Bonus features
- [ ] User can see rows in the episode table have alternating background
colors.
- [ ] User can see a summary above the episode table showing the number
of episodes for each podcast.
- [ ] User can see a clickable checkbox next to each podcast name in the
summary above the episode table.
- [ ] User can click the radio button next to the podcast name to include
episodes for that podcast in the episode table.

# QRCode Badge Generator
**Tier:** 2-Intermediate
At some point in your career you will probably find yourself involved helping
to coordinate a company-sponsored event or a local technical Meetup. It's not
uncommon in these types of gatherings for attendees to want to exchange contact
information between themselves.
But how to do that? Attendees could always exchange business cards or write
down each others email or social media account names, but that can be slow and
error prone. Wouldn't it be nice to be able to scan a each others badges to
capture this type of information quickly and more dependably?
If you answered 'Yes!" to this question then QRCode Badge Generator is an
app you will be interested in creating. The objective of this application is
to collect a meeting attendee's name, email address, Twitter, and GitHub
account names and print a name badge with a QRcode that can be scanned using
a smartphone.
### Requirements & Constraints
- For this app you'll want to use the NPM package
[QRCode Generator](https://www.npmjs.com/package/qrcode-generator) to encode
the information you collect from the attendee in a QR code.
- To test your implementation you'll need to download a QR code reader onto
your smartphone or tablet. There are many such readers that are free of charge.
Check the app store for your device to find the one that best suites your needs.
## User Stories
- [ ] User can see an input panel containing input fields for the attendee
name, email address, Twitter account name, GitHub account name, and 'Cancel'
and 'Create' buttons.
- [ ] User can enter data into these input fields. Note that attendee name
and email address are required, but the Twitter and GitHub account names are
optional fields.
- [ ] User can click the 'Cancel' button to clear all input fields as well as
the badge panel (see below) if it has been created.
- [ ] User can click the 'Create' button to generated an image of the
attendees name badge.
- [ ] User can see an error message if any of the following are true:
- Required fields are empty
- A first name and last name have not been entered
- Email input field isn't a properly formatted email address
- Twitter account name doesn't start with '@'
- [ ] User can see an badge panel displayed on screen containing this
information, plus a QR code encoded with this information.
## Bonus features
- [ ] User can see a 'Print' button below the badge panel.
- [ ] User can see the 'Print' button enabled only after the input fields
have been validated and the badge is displayed in the badge panel.
- [ ] User can make corrections to the input fields and click 'Create' to
update the contents of the badge panel.
- [ ] User can click the 'Print' button to reproduce the badge panel on a
label or hardcopy.
- [ ] User can see the '@' symbol automatically prepended to the Twitter
account name so it doesn't have to be manually entered.

# Sales Reciepts
**Tier:** 2-Intermediate
In the [First DB App](../1-Beginner/First-DB-App.md) you were able to learn the basics of
how to use the IndexedDB database that's built into the browser. In Sales
Reciepts you'll take this a step further by creating an app that records
point of sales receipts, presumably for subsequent balancing against cash in
the stores cash register.
The objective of Sales Receipts is to implement point-of-sale functionality for
a merchant and to make a record of all sales in a database.
### Requirements & Constraints
- Developer should implement this app as a frontend application that uses the
IndexedDB database in the browser to record all sales receipts.
- Developer may implement the inventory of items available for sale as an
array of objects in the application source. Each item should be defined with
the following attributes:
- Item number (unique)
- Description
- Unit price
- Developer should use her UI/UX skills to create a pleasant and efficient
window layout that makes it easy for the user to purchase items and display
purchase history.
- The primary use case for a browser based database is to maintain state or
status information that needs to persist across sessions, or as a work area for
temporary data. For example, data retrieved from a server that must be
reformatted or cleansed before it's presented to the user.
- It is important to keep in mind that since the client-side browser environment
cannot be secured you should not maintain any confidential or personal
identifying information (PII) in a browser based database.
## User Stories

# Sports Bracket Generator
**Tier:** 2-Intermediate
Whether your main sport is soccer, baseball, cricket, or competitive
Esports following the progress of your favorite team during tournaments is an
activity enjoyed by many.
Tracking team progress is traditionally done using a horizontal tree diagram
showing all of the initial matches on the lefthand side. At the end of each
match the winner advances to the next round in the tournament along with the
winner of the adjacent match. Columns in the diagram are used to represent
each round and contain one-half of the teams in the adjacent column on the left
and twice as many teams as the adjacent column to the right. The number of
teams in each column decreases from left to right until the last round
(column) contains the final winner in the tournament.
The SportsBracket Generator automates the process of creating this type of chart by
drawing it in a browser window to relieve the user from having to draw it by
hand.
## User Stories
- [ ] User can enter the name of the tournament
- [ ] User can enter the starting and ending dates of the tournament
- [ ] User can enter the number of teams competing in the tournament
- [ ] User can see a warning if either the starting or ending date is
invalid
- [ ] User can see a warning if an odd number of competing teams is entered
## Bonus features
- [ ] User can enter the competing team names for each match
- [ ] User can enter the date for each match
- [ ] User can enter the final score for each match
- [ ] User can expect that this data will persist across sessions

# StringArt
**Tier:** 2-Intermediate
The purpose of String Art is to provide the developer with practice creating a
simple animated graphic, using geometry in the animation algorithm, and
creating something that's visually pleasant to watch.
String Art draws a single multicolored line which smoothly moves until one
end touches a side of the enclosing window. At the point it touches a "bounce"
effect is applied to change it's direction.
A ripple effect is created by only retaining 10-20 images of the line as it
moves. Older images are progressively faded until they disappear.
Animation libraries are not allowed. Use only Vanilla HTML/CSS/JavaScript.
## User Stories
- [ ] Start by drawing a multicolored line at a random position within the boundary of it's enclosing window
- [ ] Each 20ms draw a new copy of the line at a new position based on a trajectory - the incremental distance from the previous line based on the endpoints
- [ ] When either endpoint of the line touches the boundary of the enclosing window change it's direction and randomly alter its angle
- [ ] Progressively fade the intensity of old lines so that only the most recent 10-20 lines are visible to create the sense of movement or "ripple"
## Bonus features
- [ ] User can specify the length of the line and it's velocity
- [ ] User can specify the multiple lines within the window, all moving along different trajectories and velocities

# Typing Practice
**Tier:** 2-Intermediate
Some things are so obvious they can be easily overlooked. As a developer
your ability to type quickly and accurately is one factor that influences
your development productivity. The objective of the Typing Practice app is
to provide you with typing practice along with metrics to allow you to
measure your progress.
Typing practice displays a word which you must then type within a specific
interval of time. If the word is incorrectly typed it stays on
screen and the time interval remains the same. But when the word is correctly
typed a new word is displayed and the time interval is slightly reduced.
Hopefully, this repetitive practice will help you improve both your typing
speed and accuracy.
## User Stories
- [ ] User can see the time interval words must be typed in displayed in
the app window.
- [ ] User can see the number of successful attempts and the number of total
attempts in a score box.
- [ ] User can click a 'Start Practice' button to start the practice session.
- [ ] User can see the prompt word displayed in a text box.
- [ ] User can begin typing the word in a text input box.
- [ ] User can see the letters that have been typed flash if an incorrect
letter is entered and the text input box will be cleared.
- [ ] User can see the a message adjacent to the text input box indicating
the user should try again if an incorrect letter is entered.
- [ ] User can see the number of total attempts incremented in the score box.
- [ ] User can see a congratulations message if the word is correctly typed.
- [ ] User can see the time interval words must be typed decremented by a
small amount if the word is correctly typed.
- [ ] User can see the number of successful attempts incremented in the score
box if the word was correctly typed.
- [ ] User can click a 'Stop Practice' button to stop the practice session.
## Bonus features
- [ ] User can hear a unique audible tone signalling when a new word is
displayed, a word is correctly entered, or an incorrect letter is typed in
the word.
- [ ] User can login to the app
- [ ] User can see cumulative performance statistics across all of his/her
practice sessions.

# Battleship Game Engine
**Tier:** 3-Advanced
Battleship Game Engine (BGE) implements the classic turn-based board game as a
package that's separated from any presentation layer. This is a type of
architectural pattern that useful in many application since it allows
any number of apps to utilize the same service.
The BGE itself is invoked through a series of function calls rather than
through directly coupled end user actions. In this respect using the BGE is
is similar to using an API or a series of routes exposed by a web server.
This challenge requires that you develop the BGE and a very thin, text-based
presentation layer for testing that's separate from the engine itself. Due to
this the User Stories below are divided two sets - one for the BGE and one
for the text-based presentation layer.
BGE is responsible for maintaining game state.
## User Stories
### BGE
- [ ] Caller can invoke a `startGame()` function to begin a 1-player game. This function will generate an 8x8 game board consisting of 3 ships having a width of one square and a length of:
- Destroyer: 2 squares
- Cruiser: 3 squares
- Battleship: 4 squares
`startGame()` will randomly place these ships on the board in any direction and will return an array representing ship placement.
- [ ] Caller can invoke a `shoot()` function passing the target row and column coordinates of the targeted cell on the game board. `shoot()` will return indicators representing if the shot resulted in a hit or miss, the number of ships left (i.e. not yet sunk), the ship placement array, and an updated hits and misses array.
Cells in the hits and misses array will contain a space if they have yet to be targeted, `O` if they were targeted but no part of a ship was at that location, or `X` if the cell was occupied by part of a ship.
### Text-based Presentation Layer
- [ ] User can see the hits and misses array displayed as a 2 dimensional character representation of the game board returned by the `startGame()` function.
- [ ] User can be prompted to enter the coordinates of a target square on the game board.
- [ ] User can see an updated hits and misses array display after taking a shot.
- [ ] User can see a message after each shot indicating whether the shot resulted in a hit or miss.
- [ ] User can see an congratulations message after the shot that sinks the last remaining ship.
- [ ] User can be prompted to play again at the end of each game. Declining to play again stops the game.
## Bonus features
### BGE
- [ ] Caller can specify the number of rows and columns in the game board as a parameter to the `startGame()` function.
- [ ] Caller can invoke a `gameStats()` function that returns a Javascript object containing metrics for the current game. For example, number of turns played, current number of hits and misses, etc.
- [ ] Caller can specify the number of players (1 or 2) when calling `startGame()` which will generate one board for each player randomly populated with ships.
`shoot()` will accept the player number the shot is being made for along with the coordinates of the shot. The data it returns will be for that player.
### Text-based Presentation Layer
- [ ] User can see the current game statics at any point by entering the phrase `stats` in place of target coordinates. (Note that this requires the `gameStats()` function in the BGE)
- [ ] User can specify a two player game is to be played, with each player alternating turns in the same terminal session (Note that this requires corresponding Bonus Features in the BGE)
- [ ] User can see the player number in prompts associated with the inputs in each turn.
- [ ] User can see both players boards at the end of each turn.

# Boole Bots Game
**Tier:** 3-Advanced
Boole Bots is a game that is not only fun, but also an aid in helping to
understand basic Boolean logic. This game has an arena of 8x8 game tiles in
which your bots move at random speeds and trajectories. The Bots are assigned
boolean values of 0 or 1 and boolean operations - AND, OR, NOR, NOT.
When a bot collides with another bot its boolean operation is applied to both
it and the other bots' boolean value to determine which one wins or looses, or
if the collision results in a tie. Loosing bots disappear and winning bots
continue moving about the arena until only one remains.
### Requirements & Constraints

### Game Configuration Panel
- [ ] User can see a game configuration panel with these subcomponents:
- Four bot panels with controls to allow the user to input a unique bot
name, select its Boolean value and operation, select the bots speed using a
slider, and a dropdown to specify its starting direction - North, South,
East, West
- [ ] User can enter a unique name for each bot into an input text box
- [ ] User can see an error message if the name entered is the same name
assigned to another bot.
- [ ] User can select the bots Boolean value (0 or 1) from a dropdown.
- [ ] User can select a bots Boolean operation from a dropdown - AND, OR, XOR,
or NOT.
- [ ] User can move the speed slider to set a bots speed
- [ ] User can select a bots starting direction from the direction dropdown.
- [ ] User can see the bot randomly assigned to a tile in the arena once its
name has been defined.
### Game Controls
- [ ] User can a button in the game control panel to 'Battle!'
- [ ] User can click the 'Battle!' button to start the bot battle in the arena.

is started.
- [ ] User can click the 'Stop!' button to halt gameplay
- [ ] User can see the 'Stop!' button text change back to 'Battle!' once a
single bot wins the match.
### Arena
- [ ] User can see bots bounce off the boundary walls of the arena in a new
direction
- [ ] User can see bots pause for an instant when they collide.
- [ ] User can see a bot disappear after colliding if the result of it's
boolean operation appied to its boolean value and that of the bot is has
collided with result in 0.
- [ ] User can see a bot that wins a collision resume its path at the same
speed and direction.
- [ ] User can see both colliding bots resume their paths at the same speed
and direction in the event of a tie. In other words, when the collision resulted
in the same boolean result (0 or 1) for both.
- [ ] User can see gameplay stop when only one bot remains.
### Leaderboard

================================================
# Calorie Counter
**Tier:** 3-Advanced
Getting and staying healthy requires a combination of mental balance,
exercise, and nutrition. The goal of the Calorie Counter app is to help the
user address nutritional needs by counting calories for various foods.
This app provides the number of calories based on the result of a user search
for a type of food. The U.S. Department of Agriculture MyPyramid Food Raw Data
will be searched to determine the calorie values.
Calorie Counter also provides you, the developer, with experience in transforming
raw data into a format that will make it easier to search. In this case, the
MyPyramid Food Raw Data file, which is an MS Excel spreadsheet, must be
downloaded and transformed into a JSON file that will be easier to load and
search at runtime (hint: take a look at the CSV file format).
## User Stories
- [ ] Developer will create a JSON file containing the food items to be
searched. This will be loaded when the app is started.
- [ ] User can see an panel containing a food description input text box,
a 'Search' button, and a 'Clear' button.
- [ ] User can enter search terms into the food description input text box.
- [ ] User can click on the 'Search' button to search for the matching food.
- [ ] User can see a warning message if no search terms were entered.
- [ ] User can see a warning message if no matches were found.
- [ ] User can see a list of the matching food items, portion sizes, and
calories in a scrollable results panel that is limited to 25 entries.
- [ ] User can click on the 'Clear' button to clear the search terms and
results list.
## Bonus features
- [ ] User can see the count of the number of matching food items adjacent to
the results list.
- [ ] User can use a wildcard character in search terms.
- [ ] User can see more than 25 entries from a search by clicking a Down
icon button to add more matching food items to the search results list.
- [ ] Developer will implement load the MyPyramid data into a database or a
data structure other than an array for faster searching.

================================================
# Elevator
**Tier:** 3-Advanced
It's tough to think of a world without elevators. Especially if you have to
walk up and down 20 flights of stairs each day. But, if you think about it
elevators were one of the original implementations of events and event handlers
long before web applications came on the scene.
The objective of the Elevator app is to simulate the operation of an elevator
and more importantly, how to handle the events generated when the buildings
occupants use it. This app simulates occupants calling for an elevator from
any floor and pressing the buttons inside the elevator to indicate the floor
they wish to go to.
### Constraints
- You must implement a single event handler for the up and down buttons on
each floor. For example, if there are 4 floors a single event handler should
be implemented rather than 8 (two buttons per floor).
- Similarly, a single event handler should be implemented for all buttons on
the control panel in the elevator rather than a unique event handler for each
button.
## User Stories
- [ ] User can see a cross section diagram of a building with four floors,
an elevator shaft, the elevator, and an up button on the first floor, up and
down buttons on the second and third floors, and a down button on the fourth
floor.
- [ ] User can see the elevator control panel with a button for each of the
floors to the side of the diagram.
- [ ] User can click the up and down button on any floor to call the
elevator.
- [ ] User can expect that clicking the up and down buttons on any floor
to request the elevator will be queued and serviced in the sequence they were
clicked.
- [ ] User can see the elevator move up and down the shaft to the floor it
was called to.
- [ ] User can click the elevator control panel to select the floor it
should travel to.
- [ ] User can expect the elevator to pause for 5 seconds waiting for a
floor button on the control panel to be clicked. If a floor button isn't
clicked within that time the elevator will process the next call request.
- [ ] User can expect the elevator to return to the first floor when there
are no requests to process.

# Fast Food Simulator App
**Tier:** 3-Advanced
Fast Food simulates the operation of a simple take-away restaurant and is
designed to help the developer put his or her knowledge of Promises and SOLID
design principles to work.
This app simulates customers of a take-away restaurant placing orders and
and waiting for them to be prepared and delivered to a pickup counter. After
placing the order the customer waits on the order to be announced before
picking it up and proceeding to the dining area.
The user stories that make up this app center around four distinct roles:
- User - the end user using the application
- Customer - the simulated Customer
- Order Taker - the simulated Order Taker
- Cook - the simulated Cook
- Server - the simulated Server
This app has quite a few User Stories. Don't be overwhelmed though. Take the
time to sketch out not just the UI, but how the different actors (roles)
interact and incrementally build the app following Agile principles.
### Constraints
- Order tickets can be represented as two different types of Promises - one
the Server waits on while the Cook prepares the order and another the Customer
waits on while in the serving line.
- Use the native equivalent of JS Promises in whichever language you choose
to develop in. JS developers should use native Promises and not `async/await`.
- Create this app using native language features. You may NOT use a simulation
package or library.
- New customers arrive in the order line at a fixed interval of time. In other
words, new customers arrive at a constant rate.
- Order tickets are fulfilled at a fixed interval of time as well. They are
completed at a constant rate.
## User Stories
### Application Operation
- [ ] User can see an input area that allows the entry of the time interval
for customer arrival and a time interval for the fulfilment of an
_order ticket_ by the cook.
- [ ] User can see a customized warning message if the customer arrival
interval or the order fulfilment interval is incorrectly entered.
- [ ] User can start the simulation by clicking on a Start button.
- [ ] User can see an order line area containing a text box showing the
number of customers waiting to place orders.
- [ ] User can see an order area containing text boxes showing the
_order number_ currently being taken.
- [ ] User can see a kitchen area containing a text box showing the
_order number_ that's being prepared and a text box listing the waiting
orders in sequence, along with a count of the number of waiting orders.
- [ ] User can see a Pickup area containing a text box showing the
_order number_ that's currently available for pickup by the Customer and a
text box showing the number of Customers waiting in the serving line.
- [ ] User can stop the simulation at any time by clicking a Stop button.
## Bonus features
- [ ] User can specify how long it takes for an Order Taker to create an
_order ticket_.
- [ ] User can specify how long it takes for the Server to deliver an order
to the customer.
- [ ] User can specify the total amount of time the simulation is to run
once the Start button has been clicked.
- [ ] User can see an animated view of Customers and orders as they move
through the workflow.

# GitHub Timeline
**Tier:** 3-Advanced
API's and graphical representation of information are hallmarks of modern
web applications. GitHub Timeline combines the two to create a visual history
of a users GitHub activity.
The goal of GitHup Timeline is accept a GitHub user name and produce a
timeline containing each repo and annotated with the repo names, the date
they were created, and their descriptions. The timeline should be one that
could be shared with a prospective employer. It should be easy to read and
make effective use of color and typography.
Only public GitHub repos should be displayed.
## User Stories
- [ ] User can enter a GitHub user name
- [ ] User can click a 'Generate' button to create and display the named
users repo timeline
- [ ] User can see a warning message if the GitHub user name is not a valid
GitHub user name.
## Bonus features
- [ ] User can see a summary of the number of repos tallied by the year they
were created
## Useful links and resources
GitHub offers two API's you may use to access repo data. You may also choose
to use an NPM package to access the GitHub API.
Documentation for the GitHub API can be found at:
- [GitHub REST API V3](https://developer.github.com/v3/)
- [GitHub GraphQL API V4](https://developer.github.com/v4/)
Sample code showing how to use the GitHub API's are:
- [GitHub REST API client for JavaScript ](https://github.com/octokit/rest.js/)
- [GitHub GraphQL API client for browsers and Node](https://github.com/octokit/graphql.js)
You can use this CURL command to see the JSON returned by the V3 REST API for
your repos:
```
curl -u "user-id" https://api.github.com/users/user-id/repos
```

# GitTweet
**Tier:** 3-Advanced
In the [GitHub Timeline](./GitHub-Timeline-App.md) app you used GitHub's API to
create a timeline of your repos. What could be more powerful that using an API
such as this? Why using two API's, of course.
The goal of GitTweet is to create a GitHub app to tweet when a pull request
is created for one of your repos.
## User Stories
- [ ] User can see an input area tabular display prepopulated with rows for
each of the GitHub repos she owns and a selection checkbox next to each repo
name, a single input date field, and a 'Scan' button.
- [ ] User can click the checkboxes in the repo list to select or deselect
repos for processing.
- [ ] User can enter a date into the date field. This defines the point after
which any new PR requests will be tweeted.
- [ ] User can click the 'Scan' button to identify repos that have had a new
PR created that has not been previously tweeted. In other words. Consecutively
entering the same date to scan from should only generate tweets for PR's that
have not yet been tweeted.
- [ ] User can see an error message if no date was entered, if it is not a
valid date, or if it is a future date.
- [ ] User can see repos highlighted if a tweet will be generated for them
and the 'Scan' button will change to 'Tweet'.
- [ ] User may deselect a repo by clicking on its checkbox. Doing this will
change the button back to 'Scan' and clicking it will repeat the search for
repos that have had new PR's (not yet tweeted) created since the scan date
entered by the user.
- [ ] User may enter an new scan date at this point which also changes the
button back to 'Scan'.
- [ ] User may click the 'Tweet' button to send a tweet bearing the following
message - `Pull Requst #<pr-number> created for repo <repo name> - <repo description>`.
- [ ] User can see this tweet send from her Twitter account.
## Bonus features
- [ ] User does not need to manually enter a scan date. If omitted the scan
will resume from the last scan date which must persist across sessions.
- [ ] User may enter a custom tweet message
- [ ] User repo selections will persist across sessions so they do not have
to be reselected each time.
