// 原型式继承 // 其基本思路是借助原型可以基于已有的对象创建新的对象 function object(o){ function F(){} F.prototype = o; return new F(); } var person = { name: "Tom", friends: ["Jack", "John", "Kim"] }; var David = object(person); David.name = "David"; David.friends.push("Amy"); console.log(David.friends);// ["Jack", "John", "Kim", "Amy"] var Rob = object(person); Rob.name = "Rob"; console.log(Rob.friends);// ["Jack", "John", "Kim", "Amy"]
