There is also a need for a completely compliant and safe markdown parser. AFAIK few parsers are as correct in edge cases as micromark. If performance is really important, consider looking at the Rust version of micromark: https://github.com/wooorm/markdown-rs

If you have specific recommendations on improving performance while keeping inline with GFM spec and being a safe parser, those recommendations are welcome.

Hi! Thanks for taking the time to contribute!

Because we treat issues as our backlog, we close duplicates to focus our work and not have to touch the same chunk of code for the same reason multiple times. This is also why we may mark something as duplicate that isn’t an exact duplicate but is closely related.
