# babel-plugin-transform-es2015-parameters
> Compile ES2015 default and rest parameters to ES5
This plugin transforms ES2015 parameters to ES5, this includes:
- Destructuring parameters
- Default parameters
- Rest parameters
## Installation
```sh
npm install --save-dev babel-plugin-transform-es2015-parameters
```
## Caveats
Default parameters desugar into `let` declarations to retain proper semantics. If this is
not supported in your environment then you'll need the
[transform-block-scoping](http://babeljs.io/docs/plugins/transform-es2015-block-scoping) plugin.
## Usage
### Via `.babelrc` (Recommended)
**.babelrc**
```json
{
"plugins": ["transform-es2015-parameters"]
}
```
### Via CLI
```sh
babel --plugins transform-es2015-parameters script.js
```
### Via Node API
```javascript
require("babel-core").transform("code", {
plugins: ["transform-es2015-parameters"]
});
```
