# ES6 `String.fromCodePoint` polyfill [](https://www.npmjs.com/package/string.fromcodepoint)
An robust & optimized polyfill for [the `String.fromCodePoint` method in ECMAScript 6](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-string.fromcodepoint).
This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](https://tc39.es/ecma262/#sec-string.fromcodepoint).
Other polyfills for `String.fromCodePoint` are available:
* by [Norbert Lindenberg](http://norbertlindenberg.com/) (passes all tests)
* by [Steven Levithan](http://stevenlevithan.com/) (fails 8 tests)
* by [Paul Miller](http://paulmillr.com/) (passes all tests)
## Installation
Via [npm](http://npmjs.org/):
```bash
npm install string.fromcodepoint
```
Then, in [Node.js](http://nodejs.org/):
```js
var fromCodePoint = require('string.fromcodepoint');
```
In a browser:
```html
```
> **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`](https://mths.be/codepointat) is available, too.
The tests for this repository [are now used by Mozilla](http://hg.mozilla.org/integration/mozilla-inbound/rev/2411714cd058), to help ensure their native `String.fromCodePoint` implementation is correct.
## For maintainers
### How to publish a new release
1. On the `main` branch, bump the version number in `package.json`:
```sh
npm version patch
```
Instead of `patch`, use `minor` or `major` [as needed](https://semver.org/).
Note that this produces a Git commit + tag.
1. Push the release commit and tag:
```sh
git push && git push --tags
```
Our CI then automatically publishes the new release to npm.
