String.fromcodepoint NPM

ES6 `String.fromCodePoint` polyfill

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:

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 as bundle.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.

How to publish a new release

On the main branch, bump the version number in package.json:
```
npm version patch
```
Instead of patch, use minor or major 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.
