A quick exercise: built a small Markdown → HTML converter in JavaScript.
Purpose:
- Stress-test string manipulation and regex-driven parsing (capture groups, flags, lazy vs greedy matching, order-dependent transforms).
- No libraries, no markdown engines — just core logic.
- Converts basic Markdown syntax (headings, bold, italics, code, lists, etc.) to HTML.
- All logic written from scratch using JavaScript's
StringandRegExpAPIs. - Simple, clean UI for input and preview (polished with CSS).
- Open
index.htmlin your browser. - Type Markdown into the left textarea.
- See the raw HTML and live preview update instantly.

- Practice advanced regex and string manipulation in JS
- Explore order-dependent parsing challenges
- No reliance on third-party libraries
This is a learning project, not a production-ready Markdown engine.
