String.fromCodePoint
polyfill
ES6 An robust & optimized polyfill for the String.fromCodePoint
method in ECMAScript 6.
This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.
Other polyfills for String.fromCodePoint
are available:
- http://norbertlindenberg.com/2012/05/ecmascript-supplementary-characters/#String by Norbert Lindenberg (passes all tests)
- https://gist.github.com/slevithan/2290602 by Steven Levithan (fails 8 tests)
- https://github.com/paulmillr/es6-shim/blob/771e98e789292706d2435e4e10ffbe45edf40da6/es6-shim.js#L63-L83 by Paul Miller (passes all tests)
Installation
Via npm:
npm install string.fromcodepoint
Then, in Node.js:
var fromCodePoint = require('string.fromcodepoint');
In a browser:
<script src="https://bundle.run/string.fromcodepoint"></script>
NOTE: It's recommended that you install this module using a package manager such as
npm
, because loading multiple polyfills from a CDN (such asbundle.run
) will lead to duplicated code.
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.
For maintainers
