JavaScript模块化来龙去脉

var Modules = (function ModulesManager() {
		var modules = {};
		function define(name,deps,impl) {
			for (var i = 0; i < deps.length; i++) {
				deps[i] = modules[deps[i]];
			}
			modules[name] = impl.apply(impl,deps);
		}
		
		function getModule(name) {
			return modules[name];
		}

		return {
			define: define,
			getModule: getModule
		};
	 })();

	Modules.define('m1',[],function f1() {
		function hello(argument) {
			return "hello"+argument;
		}
		return {
			hello:hello
		};
	})
	Modules.define('m3',[],function f1() {
		function ff(argument) {
			return "ff"+argument;
		}
		return {
			ff:ff
		};
	})
	Modules.define('m2',['m1','m3'],function f2(argument,ff) {
		debugger;
		function awesome() {
			console.log(argument)
			console.log(argument.hello("finit"))
			console.log(ff.ff("finit"))

		}
		return {
			awesome:awesome

	})

	var m2 =  Modules.getModule('m2');
	m2.awesome();

(function iife(fn){
	fn(window);
})(function def(global){
	......
