You can use the JavaScript function as class.

ClassUtil = function(param){    
     privateFunction = function(param){    
        // Do some thing    
        return valueParam;
    }    
    this.publicFunction = function(){    
        var val1 = function1();    
        if (val1){    
            return true;    
        } else{    
            return false;
        }
    }
}

function getClass(){    
   var classUtil = new ClassUtil();     
   alert(classUtil.publicFunction());    
}

There is one public and one private function. You can call public function from out side using object of the class.
