Mas na maioria das vezes estes conteúdos **são focados na mesma coisa**! A grande maioria fala sobre a Stack **MEAN** (MongoDB, Express.js, Angular.js e Node.js), programação para Web ou apenas **simples CRUDs** (as operações básicas de sistemas: Cadastrar, Listar, Atualizar e Remover), coisas que para **estudos** funcionam muito bem, mas a **realidade** no dia a dia de desenvolvimento de **aplicações** focado em **produção** é um pouco **diferente**. Este treinamento foi **desenvolvido** sob medida **baseado** em uma pesquisa sobre o que a **comunidade brasileira mais necessita**, suas principais **dificuldades** e **desafios**. Neste curso você aprenderá desde o básico de Javascript, ciclo de vida, manipulação de listas ao desenvolvimento real de aplicações em ambiente de produção. Na prática você também aprenderá conceitos sobre desenvolvimento orientado a testes, autenticação, autorização, documentação de serviços e gerenciamento de variáveis de ambiente (environments) de aplicações. ## INSTRUTOR ### [Erick Wendel](https://twitter.com/erickwendel_) Erick Wendel is a Speaker, Software Consultant and community Co-organizer on Brazil.
