I feel like people complaining about Prettier being "heavily opinionated" are missing the point. Perhaps I'm biased by my decade of using Go, but not having to worry about superfluous stylistic choices is a welcome reduction in cognitive load. (Up to a point I guess, e.g. I'd never put up with K&R-style newline opening brackets).
Prettier is very opinionated about line length which gofmt isn't. That's the only complaint I have and it's bad enough I just refuse to use it. Add one character to a line and enjoy a ten-line diff. Edit: See a contrived example of something gofmt doesn't touch (the behavior I want): https://go.dev/play/p/cKMKnFwT8tq
I really miss that gofmt applied some limit to line length. In TS I just write a too long line, and Prettier reformats it into a sensible set of consecutive lines, I don't even have to think if breaking before or after this or that parentheses or bracket. With Go, I have to, and I'd rather not.
