寄生式继承

//寄生式继承是原型继承密切相关的一种思路，。寄生式继承的思路与寄生构造函数和工厂模式类似，即创建一个仅用于封装继承过程
//的函数，该函数在内部以某种方式来增强对象，

function object(o){
function F(){}
F.prototype = o;
F.name = "shalio";
}

function createAnother(original){
var clones = object(original);
clones.sayHi = function(){
console.log("Hi");
};
return clones;
}

var person ={name:"shali",
friends:["1","s"]};

var anotherperson = createAnother(person);

anotherperson.sayHi();
