Object.create() 和 new Object()

1、Object.create的实现方式：

//对象
var elephant = {
        weight() {
            console.log("overweight");
        },
        ear() {
            console.log("big");
        }
    }

/* 一、Object.create()实现*/
//实现
Object.create( elephant )


//Object.create()实现原理
Object.create =  function ( elephant ) {
    var F = function () {};
    F.prototype = elephant;
    return new F();
};


/* 二、new Object()实现*/
//实现
var animal = new elephant();

//new Object()实现原理
var animal = new Object();
animal.__proto__ = Base.prototype;
elephant.call(animal);
