// formats
// ------------------------------------------------------------------------------------------
// amd – Asynchronous Module Definition, used with module loaders like RequireJS
// cjs – CommonJS, suitable for Node and Browserify/Webpack
// esm – Keep the bundle as an ES module file
// iife – A self-executing function, suitable for inclusion as a <script> tag. (If you want to create a bundle for your application, you probably want to use this, because it leads to smaller file sizes.)
// umd – Universal Module Definition, works as amd, cjs and iife all in one
// system – Native format of the SystemJS loader
