A robust & optimized `String.prototype.includes` polyfill, based on the ECMAScript 6 specification.

Package Exports

  • string.prototype.includes

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (string.prototype.includes) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.
