+
+[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.
