Several ways to create JavaScript objects

ECMAScript provides the following objects: String, Date, Array, Boolean, Math, number, REGEXP, Global

Many custom JS objects need to be used in the program

1. Create directly

var obj = new Object ();

Obj.username = "Jinxiao";

Obj.age = 26;

Alternative to this method is: var obj = {username: "Jinxiao", age:26};

2. Constructor creation

function Obj (username,age) {

This.username = Username;

This.age = age;

}

var obj1 = new OBJ ("Jinxiao", 26);

var obj2 = new OBJ ("Brotherxiao", 27);
