职责划分得很明确，命名这些也很达意。看下来有两点是不是可以优化：1. Watcher 也可以通过 defineProperty get 的方式延迟初始化；2. 当依赖发生变更后，deps 可以只标记为脏的，等真正使用时再计算，这个也可以放到上一条的 get 里做

将对象中的属性和方法分开: 1、在Observable类中将对象的属性变得可观察，即使用defineProperty设置属性的get和set方法，返回一个新的对象。2、Watcher类会调用原对象的方法为新对象创建一个与方法同名的属性，同时会为方法访问到的属性的setter()上加上对应的回调函数。当属性改变时，会调用绑定的回调函数，修改依赖该属性的其他属性值。
