ES6 String.prototype.codePointAt
polyfill
A robust & optimized polyfill for the String.prototype.codePointAt
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.prototype.codePointAt
are available:
- http://norbertlindenberg.com/2012/05/ecmascript-supplementary-characters/#String by Norbert Lindenberg (fails some tests)
- https://gist.github.com/slevithan/2290602 by Steven Levithan (fails some tests)
- https://github.com/paulmillr/es6-shim/blob/8e570a4b425a80f9b13ff027dbd28d65f201a319/es6-shim.js#L171-L183 by Paul Miller (
fails some testspasses all tests)
Installation
Via npm:
npm install string.prototype.codepointat
Then, in Node.js:
require('string.prototype.codepointat');
// On Windows and on Mac systems with default settings, case doesn’t matter,
// which allows you to do this instead:
require('String.prototype.codePointAt');
In a browser:
<script src="https://bundle.run/string.prototype.codepointat"></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.fromCodePoint
is available, too.
For maintainers
How to publish a new release
-
On the
main
branch, bump the version number inpackage.json
:npm version patch -m 'Release v%s'
Instead of
patch
, useminor
ormajor
as needed.Note that this produces a Git commit + tag.
-
Push the release commit and tag:
git push && git push --tags
Our CI then automatically publishes the new release to npm.
