The JavaScript reference type--object type

1. Two ways to create objects:

The new operator is followed by the Object constructor;

var obj=New  Object (); Obj.name= ' big head son '; obj.age= 12;

Object literal expression method

var obj={   name:' big head son ', age   :n};

2. two ways to Access object Properties :

Console.log (obj["name"]); Console.log (obj.age); /* Big head son */

Functionally, there is no difference between the two methods of accessing object properties. But the advantage of square brackets is that you can access the property by variable.

Example:

var obj={    name:' big head Son '}; var objname= "name"; Console.log (obj.objname); Console.log (Obj[objname]); /* */
