# ES6 `String.fromCodePoint` polyfill [![string.fromcodepoint on npm](https://img.shields.io/npm/v/string.fromcodepoint)](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.
