Intro

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.

This particular instance of Prettier includes one of my opinions for formatting JavaScript: Stroustrup-style block formatting, which vertically aligns all the keywords used in if-then-else, try-catch-finally, and do-while statements.

Input

foo(reallyLongArg(), omgSoManyParameters(), IShouldRefactorThis(), isThereSeriouslyAnotherOne());

Output

foo(
  reallyLongArg(),
  omgSoManyParameters(),
  IShouldRefactorThis(),
  isThereSeriouslyAnotherOne(),
);

Prettier can be run in your editor on-save, in a pre-commit hook, or in CI environments to ensure your codebase has a consistent style without devs ever having to post a nit-picky comment on a code review ever again!
