There was a problem hiding this comment.
This looks ok, but I'm curious did you run into a real life problem that you're trying to solve or...?

Fix: Discord uses getLanguage to validate that a language specified exists in highlightJS and retrieve metadata about the language for code block highlighting in chat. Because highlightJS returns prototype values instead of the highlight languages themselves, the result is a few different bugs in our clients which expect the return type to be only `Language | undefined`.

getLanguagecurrently returns values for object prototype method names. By swapping to objects with a null prototype, we can fix this weird behavior.
