ES2015 parameters transform

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.

Usage

.babelrc

{
  "plugins": ["transform-es2015-parameters"]
}

Via CLI

babel --plugins transform-es2015-parameters script.js

Via Node API

require("babel-core").transform("code", {
  plugins: ["transform-es2015-parameters"]
});
