Maybe the guy you're replying to edited his post, but "If it's a JavaScript framework, please give code examples in JavaScript"--to me--reads as a rather polite request, rather than a dictum as you suggested.

But there are other problems with the comment.

There's no mention of CoffeeScript anywhere

It's in the 2nd paragraph of the docs. Not prominent, but somewhere.

CoffeeScript is not JavaScript

Technically true, I suppose, but they are beyond related.

If it's a JavaScript framework

Maybe it's a CoffeeScript framework? My sense is that at the very least, the use of CoffeeScript is an important aspect of the project.
