The name of the object. Property name =function () {} to add a method to the

var box=new boject ();

Method 2:

{} Custom objects in curly braces
In curly braces, multiple sets of attributes, which we must use, are separated by commas.

Property name (function name): function () {}//Add method to Object
}

The method used:

对象.属性名

var box{

Age:12,

Run:function () {}

}

The way to use it is, box.name

Method 3

A custom object in function form (the function is an object in JS)
function Object Name () {
this. property name = value; Adding properties to an object

}

function box（）{
this.name="user";
this.age=30;

}

var box2= new box（）；
