## 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

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

### Output

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

Prettier can be run [in your editor](https://prettier.io/docs/editors) on-save, in a [pre-commit hook](https://prettier.io/docs/precommit), or in [CI environments](https://prettier.io/docs/cli#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!
