## 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.
### Input
<!-- prettier - ignore -->
```js
foo(reallyLongArg(), omgSoManyParameters(), IShouldRefactorThis(), isThereSeriouslyAnotherOne());
```
### Output
```js
foo(
reallyLongArg(),
omgSoManyParameters(),
IShouldRefactorThis(),
isThereSeriouslyAnotherOne()
);
```

Prettier can be run [in your editor ](https://prettier.io/docs/en/editors.html ) on-save, in a [pre-commit hook ](https://prettier.io/docs/en/precommit.html ), or in [CI environments ](https://prettier.io/docs/en/cli.html#list-different ) to ensure your codebase has a consistent style without devs ever having to post a nit-picky comment on a code review ever again!
