The key point here is that the formatter has to be sufficiently advanced to know to do the right thing the vast majority of the time. Once it gets there, and once you've gotten used to the code it produces, it's better. Note that the "prettier" formatter will do the right thing in JS here, at least with the default config. It will even switch "\"string\"" to '"string"' for you.

Linting is a bit of a different beast, because linting includes changes to the code behavior itself, not just syntax. In JS there are so many footguns, that linting can often be pretty involved/strict. I think most of the people who don't like linting in JS either aren't aware of the footguns, or don't do very much code review and haven't worried themselves much with "what sort of bizare and unusual ways can this fail" sort of a thing.
