# Module Loader Polyfill

Check the console in your browser developer tools! This code is currently loaded in the page:

      <script src="../node_modules/traceur/bin/traceur.js"></script>
      <script src="../dist/es6-module-loader-dev.js"></script>
      <script type="module">
        import { hello } from 'test1.js';
        console.log(hello); // -> world

        // es6 syntax
        var a, b;
        [a, b] = [1, 2];
        console.log(a); // 1
      </script>

Click on the button below and this function will be run:

      <script>
        function buttonClick() {
          // dynamic loading API
          System.import('test2.js').then(function(module) {
            new module.Foo();
          });
        }
      </script>

Note that if you click on the button again, a new Foo module will be created, but 'test2' will not be reloaded.
