Hi all,
I had a question about the javascript implementation [commonmark.js](https://github.com/jgm/commonmark.js).
What’s the difference between html.js and renderer/html.js? It seems like the former isn’t used at all. I was going to write my own html renderer, and didn’t know which one to look at. It seems like the library uses renderer/html.js.
If anyone has info on it, it’d be appreciated, thanks.

What do you mean? In that repo there’s only one file named `html.js`: `lib/render/html.js`.
Can you rephrase your question?

There’s an extraneous html.js outside of renderer. No worries, I got the
answer from the maintainer. He said the one outside of renderer is
vestigial.
