### splitLines

Splits a multiline string into an array of lines.

Use `String.split()` and a regular expression to match line breaks and create an array.

```js
const splitLines = str => str.split(/\r?\n/);
```

```js
splitLines('This\nis a\nmultiline\nstring.\n'); // ['This', 'is a', 'multiline', 'string.' , '']
```
