* 面向对象编程思想，都有类的概念，但是js没有类，但是可以通过构造函数模拟类，通过原型对象机继承，继承的目的是为了共享数据
|
||||
* 原型的作用之一：共享数据，节省内存
|

* 原型的作用之二：实现继承

* 多态 同一对象的不同行为或者同一行为针对同一对象产生的不同效果，现有继承后有多态

|
||||
* 原型的作用
|
||||
1. 数据共享
|
||||
2. 节省内存
|
||||
* 实现继承 ----> 数据共享
|
||||
* 通过原型进行继承
|
||||
* 缺陷：因为改变原型指向实现继承，必须同时进行初始化赋值，所以导致属性重复，如果想改变属性，只有通过调用对象属性重新赋值
