Is it possible to give javascript partial class behavior like C# or monkey patching like Ruby does?

Question

The idea behind partial classes is that you can group certain functions together. The best example of this in C# is putting control definitions in one file and the event han

Answer 1

Redefine the type through inheritance approach like this:

var Dog = Class.extend({
    init:function(data){
         data = data || {};
         this.name = data.name;
    },
    run:function(){ 
        /*impl*/
    }
});

/*other js file that require first file */
var Dog = Dog.extend({
   init:function(data){ 
       this._super(data); 
   },
   bark:function(){ 
       return 'woof';
   }
});

The only problem in this approach is the dependency management, but it works.

obs: using John Resing class.js, but could be written in typescript, ES6, AngularJs, ... and many other libraries.
