In addition to the functions mentioned in the CommonMark and GFM specifications (table of contents, tables, task lists, footnotes, etc.), MarkdownParse also has the following additional features:

1. **Mermaid syntax support:** Easily create various charts using Mermaid syntax
2. **MathJax formula rendering:** Supports rendering mathematical formulas using MathJax  
3. **Intelligent resource loading:** According to actual rendering needs, it can intelligently identify whether to load required rendering resources without worrying about introducing redundant resources
4. **Image lazy loading:** Supports native image lazy loading technology in browsers, [MDN-Lazy loading](https://developer.mozilla.org/en-US/docs/Web/Performance/Lazy_loading)
5. **Text highlight:** Realize text highlight effect through `<mark>` HTML tag, [MDN-Mark](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/mark)
