[Array Flat Polyfill] is a polyfill for `Array.prototype.flat` and
`Array.prototype.flatMap`, following the [TC39 Proposal].

```sh
npm install array-flat-polyfill --save
```

The `flat()` method creates a new array with all sub-array elements
concatenated into it recursively up to the specified depth.

```js
[1, 2, [3, 4, [5, 6]]].flat(2) // [1, 2, 3, 4, 5, 6]
```

The `flatMap()` method maps each element using a mapping function, then
flattens the result into a new array.

```js
[1, 2, 3, 4].flatMap(x => [x * 2]); // [2, 4, 6, 8]
```

The script is 261 bytes when minified and gzipped. It works in all browsers,
going as far back as Internet Explorer 9.

## Usage

For immediate usage, add this script to your document:

```html
<script src="https://unpkg.com/array-flat-polyfill"></script>
```

For Node usage, add [Array Flat Polyfill] to your project:

```sh
npm install array-flat-polyfill
```

Include [Array Flat Polyfill] in your JS:

```js
import 'array-flat-polyfill';
```
