# vjs.CoreObject

__DEFINED IN__: [src/js/core-object.js#L52](https://github.com/videojs/video.js/blob/master/src/js/core-object.js#L52)  

Core Object/Class for objects that use inheritance + contstructors

To create a class that can be subclassed itself, extend the CoreObject class.

    var Animal = CoreObject.extend();
    var Horse = Animal.extend();

The constructor can be defined through the init property of an object argument.

    var Animal = CoreObject.extend({
      init: function(name, sound){
        this.name = name;
      }
    });

Other methods and properties can be added the same way, or directly to the
prototype.

   var Animal = CoreObject.extend({
      init: function(name){
        this.name = name;
      },
      getName: function(){
        return this.name;
      },
      sound: '...'
   });

   Animal.prototype.makeSound = function(){
     alert(this.sound);
   };

To create an instance of a class, use the create method.

   var fluffy = Animal.create('Fluffy');
   fluffy.getName(); // -> Fluffy

Methods and properties can be overridden in subclasses.

    var Horse = Animal.extend({
      sound: 'Neighhhhh!'
    });

    var horsey = Horse.create('Horsey');
    horsey.getName(); // -> Horsey
    horsey.makeSound(); // -> Alert: Neighhhhh!
