Object.create详解

使用现有的对象来提供新创建的对象的__proto__，说句人话就是创造原型的一种方式

 var anotherObject = {
            name: 'wuhua'
        };
        var newObject = Object.create(anotherObject, {
            age: {
                value: 18,
            },
        });

上面对象的方式实现很流畅，原型也是对象所以也没问题的啦…

  function GrandFather() {
        }
        GrandFather.prototype.name = "grandFather";
        GrandFather.prototype.setName = function () {
        }
        function Son() {
        }
        var son = Object.create(GrandFather.prototype);

验证对象原型的api
方式一

Object.getPrototypeOf(对象)

方式二

对象.__proto__

        function GrandFather() {
        }
        GrandFather.prototype.name = "grandFather";
        GrandFather.prototype.setName = function () {
        }
        function Son() {
        }
        var son = Object.create(GrandFather.prototype);
        console.log(son.__proto__)
        console.log(Object.getPrototypeOf(son))
