JavaScript创建对象的三种方法

var game = {  
     first : "吃鸡",  
     two : "英雄联盟",  
 }  
 console.log(game.first)   // 输出"吃鸡"  
 //对象的添加       
 obj.three = "王者荣耀"   
 console.log(game)   //会输出以上三个信息  
 //对象的删除  
 delete game.two   
 console.log(game.two)   //输出undefined  

var game = {}    //创建空对象  

var game = new 函数名(); 

function Game = {  
    this.first = "吃鸡";  
    this.two = "英雄联盟";  
    this.three = "王者荣耀";  
}  
//用new关键字调用  
var game = new Game()  
console.log(game.first)  //输出"吃鸡"  

var game = Object();  
game.first = "吃鸡";  
game.two = "王者荣耀";  
console.log(game.first)   //输出"吃鸡"  

var game = {  
    first : "吃鸡",  
    two : "王者荣耀",  
}  
var game_1 = Object.create(game);  
console.log(game_1.first)   //输出"吃鸡"
