Isaac's Module Idea

client.js

let {sum, pi} = import './math.js';

alert('2n = ' + sum(pi, pi));

cyclic1.js

let O = import './cyclic2.js';

export { even: function(n) { return n == 0 || O.odd(n - 1); } };

cyclic2.js

// `cyclic1.js`' exports are evaluated at runtime, so this throws an error.
let E = import './cyclic1.js';

export { odd: function(n) { return n != 0 && E.even(n-1); } };

dynload.js

Loader.load('http://json.org/modules/json2.js',
  function(JSON) {
    alert(JSON.stringify([0, {a: true}]));
});

math.js

// A simple math module.

export {
  sum: function(x, y) {
    return x + y;
  },
  pi: 3.141593,
};

nested.js

let widgets = import './widgets.js';

let {messageBox, confirmDialog} = widgets.alert;

reflecting.js

let M = import './math.js';

alert('2n = ' + M.sum(M.pi, M.pi));

renaming.js

let drawShape = shape.draw;
let drawGun = cowboy.draw;

web.html

<script module="JSON" src="http://json.org/modules/json2.js"></script>
<script module="YUI" src="http://developer.yahoo.com/modules/yui3.js"></script>

<script>
alert(JSON.stringify({'hi': 'world'}));

alert(YUI.dom.Color.toHex('blue'));
</script>

widgets.js

export {
  button: import './button.js',
  alert: import './alert.js',
  textarea: import './textarea.js',
};

The renaming example is backwards. Should be:

let drawShape = shape.draw;
let drawGun = cowboy.draw;
