marked
marked is a classic Markdown parser in JavaScript. I really don't like it! I don't recommend it! The people who made it and worked on it are great, but I think you really shouldn't use it.
- It supports a non-standard variation of Markdown, so you can't easily switch to another parser once you've encouraged people to write "in the marked style"
- It allows but doesn't sanitize HTML, which promotes a lot of XSS attacks
- It doesn't use an intermediate AST like remark or support plugins.
