class类是构造函数的另一种写法,仍然存在prototype方法 console.log(Cat.prototype);//object 可以通过原型prototype修改类方法和新增方法 Cat.prototype.Say = function(){ return return '我的名字是' + this.name+',我是原型prototype声明同样的Say方法,把原有Say方法覆盖了'; } cat2 = new Cat('年年',5)...

(即猫对象) 这时继承的关键 * * 在js中每个对象,都有一个_proto_ 指向其原型对象 * 原型对象也是对象,也有_proto_ * * 原型的原型的原型的原型: 对象总有原型 * 默认原型,其实是空对象,空对象上有一个construct 构造属性 * construct属性 又指向 new出来的对象,所有空对象表现出自己本身,而不是object * ...
Weâll see that these concepts donât really map very naturally to the object mechanism in JS, and the efforts (mixins, etc.) many JavaScript developers expend to overcome such challenges. Note This chapter spends quite a bit of time (the first half!) on heavy object-ori...
Functions在JavaScript中是作为 'first class objects' 存在的。这意味着JS中的functions是一种特殊类型的object,objects 可以做的事情,functions 都可以做。 实际上functions就像是variables 以下列举了关于objects的一些重要的事情(在JS中你也可以用function做同样的事情)。
