JavaScript对象的四种创建方法

 /* 1.基于对象字面量 */
 let girlFriend = {
     name: "萝莉",
     age: 18,
     getName: function() {
         return this.name
     },
     address: {
         name: '北京市',
         code: '10000'
     }
 }

 // 2. 利用new Object方式创建对象
 function GirlFriend(name, age, address) {
     this.name = name
     this.age = age
     this.address = address
     this.setName = function() {
         return (this.name)
     }
 }
 //利用new 来创建对象
 var girlFriend1 = new GirlFriend("萝莉", 18, {
     name: '北京市',
     code: '10000'
 })

 // 3. 基于构造函数
 function GirlFriend(name, age, address) {
     this.name = name
     this.age = age
     this.address = address
     this.setName = function() {
         return (this.name)
     }
 }
 //利用new 来创建对象
 var girlFriend1 = new GirlFriend("萝莉", 18, {
     name: '北京市',
     code: '10000'
 })

 // 4.基于工厂方法
 function createGirlFriend(name, age, address) {
     let o = new Object();
     o.name = name;
     o.age = age;
     o.address = address;
     o.setName = function() {
         return this.name
     }
     return o;
 }
 let girlFriend = createGirlFriend('萝莉', 18, {
     name: '北京市',
     code: '10000'
 })
