MyObj.js

(function(window, undefined) {
    
    var MyObj = (function () {
        var MyObj = function () {
            return new MyObj.fn.init();
        };
        
        MyObj.fn = MyObj.prototype = {
            init : function () {
                return this;
            },
            count : function () {
                for(var i in this) {
                    if (this.hasOwnProperty(i)) {
                        console.log("Element "+i+" is "+this[i]);
                    }
                }
            }
        };
        
        MyObj.fn.init.prototype = MyObj.fn;
        
        MyObj.test = 'yay';
        
        return MyObj;
    }());
    
    window.MyObj = MyObj;
   
}(window));
