The problem with doing the same in JS is that the language has been around much longer, and wasn't designed for use with a formatter. ASI failures is a great example.

Prettier has so far resisted configuration wherever possible; it has 8 options, compared with eslint's 260+.

While I understand the reasons for this (especially with the culture, for lack of a better word, around Go), I feel like this is a step backward in general. The "standard" Haskell formatter, hindent, did something similar. I found the maintainer's behavior admirable -- the style that was agreed on was very different from his own, but it was what he saw after analyzing publicly available code -- but what's the problem with custom formats if they're consistent across a whole codebase?
