## 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 ran [in your editor](http://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 comment on a code review ever again!
