array-includes Version Badge

github actions coverage dependency status dev dependency status License Downloads

npm badge

An ES7/ES2016 spec-compliant Array.prototype.includes shim/polyfill/replacement that works as far down as ES3.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the proposed spec.

Because Array.prototype.includes depends on a receiver (the this value), the main export takes the array to operate on as the first argument.

Engines that need this package include:

  • IE (all versions)
  • Safari < 9
  • Firefox < 43, and 99-101
  • Chrome < 47
  • Edge < 14
  • node < 6

Getting started

npm install --save array-includes

Usage

Basic usage: includes(array, value[, fromIndex=0])

var includes = require('array-includes'); var assert = require('assert'); var arr = [ 'one', 'two' ]; includes(arr, 'one'); // true includes(arr, 'three'); // false includes(arr, 'one', 1); // false

Example

var arr = [ 1, 'foo', NaN, -0 ]; assert.equal(arr.indexOf(0) > -1, true); assert.equal(arr.indexOf(-0) > -1, true); assert.equal(includes(arr, 0), true); assert.equal(includes(arr, -0), true); assert.equal(arr.indexOf(NaN) > -1, false); assert.equal(includes(arr, NaN), true); assert.equal(includes(arr, 'foo', 0), true); assert.equal(includes(arr, 'foo', 1), true); assert.equal(includes(arr, 'foo', 2), false); /* when Array#includes is not present */ delete Array.prototype.includes; var shimmedIncludes = includes.shim(); assert.equal(shimmedIncludes, includes.getPolyfill()); assert.equal(arr.includes('foo', 1), includes(arr, 'foo', 1)); /* when Array#includes is present */ var shimmedIncludes = includes.shim(); assert.equal(shimmedIncludes, Array.prototype.includes); assert.equal(arr.includes(1, 'foo'), includes(arr, 1, 'foo'));

Tests

Simply clone the repo, npm install, and run npm test
