## Usage
|
|
|
|
### Via `.babelrc` (Recommended)
|
|
|
|
**.babelrc**
|

}
|
|
```
|
|
|
|
## Options
|
|
|
|
This plugin will use babel's `extends` helper, which will polyfill `Object.assign` by default.
|
|
|
|
* `useBuiltIns` - Do not use Babel's helper's and just transform to use the built-in method (Disabled by default).
|
|
|
|
```js
|
|
{
|
|
"plugins": [
|
|
["transform-object-rest-spread", { "useBuiltIns": true }]
|
|
]
|
|
}
|
|
|
|
// source
|
|
