代码详解javascript模块加载器

var MyModules = (function Manager() {  var modules = {};  function define (name, deps, impl) {    for(var j = 0, length = deps.length; j < length; j++){      deps[j] = modules[deps[j]];    }    modules[name] = impl.apply(impl, deps);  }  function get (name) {    return modules[name];  }  return {    define: define,    get: get  }})();

MyModules.define('test1', [], function() {  function hello(name) {    console.log(name);  }    return {    hello: hello  }});MyModules.define('test2', ['test1'], function(test1) {  function age(name, age) {    console.log(test1.hello(name));    console.log(age);  }    return {    age: age  }});MyModules.get('test2').age('mumu', '27');
