define.js is a minimalist module system for js
define(function one() {
return 1;
});
define(function two(one) {
return one + one;
});// modules may be anonymous
define(function(window, one, two) {
window.console.log('The sum of one and two is ', one + two);
});// modules may be stateful
define(function counter() {
var calls = 0;
return function() { return ++calls; };
});
define(function(window, counter) {
window.console.log(counter(), counter());
});// modules may be safe
define(function(notDefined) {
// throws an error!
});
