Compile ES2015 default and rest parameters to ES5
This plugin transforms ES2015 parameters to ES5, this includes:
npm install --save-dev babel-plugin-transform-es2015-parameters
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.
.babelrc
(Recommended).babelrc
{ "plugins": ["transform-es2015-parameters"] }
babel --plugins transform-es2015-parameters script.js
require("babel-core").transform("code", { plugins: ["transform-es2015-parameters"] });
