ES6 String.prototype.includes polyfill Build status

A robust & optimized ES3-compatible polyfill for the String.prototype.includes method (previously known as String.prototype.contains) in ECMAScript 6.

Other polyfills for String.prototype.includes are available:

Installation

In a browser:

<script src="includes.js"></script>

Via npm:

npm install string.prototype.includes

Then, in Node.js:

require('string.prototype.includes');

// On Windows and on Mac systems with default settings, case doesn’t matter,
// which allows you to do this instead:
require('String.prototype.includes');

Notes

Polyfills + test suites for String.prototype.startsWith and String.prototype.endsWith are available, too.
