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

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 plugin.

}

Via CLI
