|
||||
|
||||
An ESnext spec-compliant `Array.prototype.findLastIndex` 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.findLastIndex` 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.findlastindex
|
||||
```
|
||||
|
||||
## Usage/Examples
|
||||
|
||||
```js
|
||||
var findLastIndex = require('array.prototype.findlastindex');
|
||||
var assert = require('assert');
|
||||
|
||||
var arr = [1, [2], [], 3, [[4]]];
|
||||
var isNumber = function (x) { return typeof x === 'number' };
|
||||
|
||||
assert.deepEqual(findLastIndex(arr, isNumber), 3);
|
||||
```
|
||||
|
||||
```js
|
||||
var findLastIndex = require('array.prototype.findlastindex');
|
||||
var assert = require('assert');
|
||||
/* when Array#findLastIndex is not present */
|
||||
delete Array.prototype.findLastIndex;
|
||||
var shimmed = findLastIndex.shim();
|
||||
|
||||
assert.equal(shimmed, findLastIndex.getPolyfill());
|
||||
assert.deepEqual(arr.findLastIndex(isNumber), findLastIndex(arr, isNumber));
|
||||
```
|
||||
|
||||
```js
|
||||
var findLastIndex = require('array.prototype.findlastindex');
|
||||
var assert = require('assert');
|
||||
/* when Array#findLastIndex is present */
|
||||
var shimmed = findLastIndex.shim();
|
||||
|
||||
assert.equal(shimmed, Array.prototype.findLastIndex);
|
||||
assert.deepEqual(arr.findLastIndex(isNumber), findLastIndex(arr, isNumber));
|
||||
```
|
||||
|
||||
