+
+An ES2019 spec-compliant `Array.prototype.flatMap` shim/polyfill/replacement that works as far down as ES3.
+
+This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](https://tc39.es/ecma262/#sec-array.prototype.flatmap).
+
+Because `Array.prototype.flatMap` depends on a receiver (the `this` value), the main export takes the array to operate on as the first argument.
+
+## Getting started
+
+```sh
+npm install --save array.prototype.flatmap
+```
+
+## Usage/Examples
+
+```js
+var flatMap = require('array.prototype.flatmap');
+var assert = require('assert');
+
+var arr = [1, [2], [], 3];
+
+var results = flatMap(arr, function (x, i) {
+	assert.equal(x, arr[i]);
+	return x;
+});
+
+assert.deepEqual(results, [1, 2, 3]);
+```
+
+```js
+var flatMap = require('array.prototype.flatmap');
+var assert = require('assert');
+/* when Array#flatMap is not present */
+delete Array.prototype.flatMap;
+var shimmedFlatMap = flatMap.shim();
+
+var mapper = function (x) { return [x, 1]; };
+
+assert.equal(shimmedFlatMap, flatMap.getPolyfill());
+assert.deepEqual(arr.flatMap(mapper), flatMap(arr, mapper));
+```
+
+```js
+var flatMap = require('array.prototype.flatmap');
+var assert = require('assert');
+/* when Array#flatMap is present */
+var shimmedIncludes = flatMap.shim();
+
+var mapper = function (x) { return [x, 1]; };
+
+assert.equal(shimmedIncludes, Array.prototype.flatMap);
+assert.deepEqual(arr.flatMap(mapper), flatMap(arr, mapper));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`
