# Polyfill
|
|
|
|
6to5 includes a polyfill that includes a custom
|
|
[regenerator runtime](https://github.com/facebook/regenerator/blob/master/runtime.js) and
|
|
[core.js](https://github.com/zloirock/core-js).
|
|
|
|
This will emulate a full ES6 environment. This polyfill is automatically loaded
|
|
when using [6to5-node](usage.md#node) and [6to5/register](usage.md#register-hook).
|
|
|
|
## Usage
|
|
|
|
### Node
|
|
|
|
You need to include the polyfill require at the top the **entry point** to your
|
|
application.
|
|
|
|
```javascript
|
|
require("6to5/polyfill");
|
|
```
|
|
|
|
### Browser
|
|
|
|
Available from the `browser-polyfill.js` file within the 6to5 directory of an
|
|
npm release. This needs to be included **before** all your compiled 6to5 code.
|
|
You can either prepend it to your compiled code or include it in a `<script>`
|
|
before it.
