Compile ES2015 constants to ES5
$ npm install babel-plugin-transform-es2015-constants
.babelrc
(Recommended).babelrc
{
"plugins": ["transform-es2015-constants"]
}
$ babel --plugins transform-es2015-constants script.js
require("babel-core").transform("code", {
plugins: ["transform-es2015-constants"]
});
This transform on its own will compile const
to let
. If you need it to compile down to var
then you must also install and enable transform-es2015-block-scoping
.
