ES6 String.fromCodePoint polyfill Build status Code coverage status

An robust & optimized ES3-compatible polyfill for the String.fromCodePoint method in ECMAScript 6.

Other polyfills for String.fromCodePoint are available:

Installation

In a browser:

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

Via npm:

npm install string.fromcodepoint

Then, in Node.js:

require('string.fromcodepoint');

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

Notes

A polyfill + test suite for String.prototype.codePointAt is available, too.

The tests for this repository are now used by Mozilla, to help ensure their native String.fromCodePoint implementation is correct.
