|
||
## Installation
|
||
|
||
In a browser:
|
||
|
||

|
||
<script src="codepointat.js"></script>
|
||
```
|
||
|
||
Via [npm](http://npmjs.org/):
|
||
|
||
```bash
|
||
npm install string.prototype.codepointat
|
||
```
|
||
|
||
Then, in [Node.js](http://nodejs.org/):
|
||
|
||
```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');
|
||
```
|
||
|
||
