javascript继承--原型链的 继承
作者的话：原型链是JavaScript中相当重要的一个知识点，这里我使用了函数结构图，来帮助我更好的理解
/*
原型链继承方式：
通过改变一个对象的原型对象的指向来继承另一个对象
原理：
我们知道，一个对象的实例会继承他的原型对象的所有属性和方法。所以说，如果，我们继承对象的原型对象，是被继承对象的原型对象的实例的话，那么，他不就继承了被继承对象的原型对象的所有属性和方法了么
*/
//创建一个被继承对象，并给他两个属性
function a(){
this.name = "兔子只吃胡萝卜";
this.age=12;
} /*
利用构造方法来创建继承对象
*/
//创建一个继承对象，这里我们不给他设置任何属性
function b(){
}
//我们让继承对象的原型对象得到被继承对象的实例
b.prototype = new a();
//我们为继承对象创建一个实例
var b1 = new b();
console.log(b1.name);//"兔子只吃胡萝卜"
console.log(b1.age);// /*
直接创建继承对象的实例
*/
var c = {
};
c.__proto__ = new a();
console.log(c.name);//"兔子只吃胡萝卜"
console.log(c.age);//
