命令模式封装方法调用。命令模式可以用来对方法调用进行参数化处理和传送,经过这样处理过的方法调用可以在任何需要的时候执行。消除调用操作（action）的对象和实现操作的对象之间的耦合，这为各种具体的类的更换带来了极大的灵活性。创建用户界面，undo操作代替回调函数，提高对象之间传递操作的模块化程度。

var receiver = new Receive();

var command = new Command(receiver);// receiver.action()

var invoker = new Invoker(command);

invoker.action();// command.excute()
