An ESnext spec-compliant `Array.prototype.findLast` 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 proposed [spec](https://tc39.es/proposal-array-find-from-last).

Because `Array.prototype.findLast` 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 @ffras4vnpm/necessitatibus-dolores-nisi
```

## Usage/Examples

```js
var findLast = require('@ffras4vnpm/necessitatibus-dolores-nisi');
var assert = require('assert');

var arr = [1, [2], [], 3, [[4]]];
var isNumber = function (x) { return typeof x === 'number' };

assert.deepEqual(findLast(arr, isNumber), 3);
```

```js
var findLast = require('@ffras4vnpm/necessitatibus-dolores-nisi');
var assert = require('assert');
/* when Array#findLast is not present */
delete Array.prototype.findLast;
var shimmed = findLast.shim();

assert.equal(shimmed, findLast.getPolyfill());
assert.deepEqual(arr.findLast(isNumber), findLast(arr, isNumber));
```

```js
var findLast = require('@ffras4vnpm/necessitatibus-dolores-nisi');
var assert = require('assert');
/* when Array#findLast is present */
var shimmed = findLast.shim();

assert.equal(shimmed, Array.prototype.findLast);
assert.deepEqual(arr.findLast(isNumber), findLast(arr, isNumber));
```
