js怎么创建对象

有多种方式创建对象，以下是其中的几种方式：

1.通过对象字面量创建对象：

let obj = {

name: "John",

age: 30,

city: "New York"

};

2.通过 Object 构造函数创建对象：

let obj = new Object();

obj.name = "John";

obj.age = 30;

3.通过构造函数创建对象：

function Person(name, age, city){

this.name = name;

this.age = age;

this.city = city;

}

let person = new Person("John", 30, "New York");

4.通过原型创建对象：

let person = {};

person.__proto__ = {

name: "John",

age: 30,

city: "New York"

};

5.通过 Object.create() 方法创建对象：

let person = Object.create({

name: "John",

age: 30,

city: "New York"

});
