var valdiate = (function() {  

     var _p={};//toss all private members into a single object.
     _p.list=[];
     _p.init=function(){
       _p.list=[];
     };

    var noDigits = function() {

    };

    //public members. use "this" to reference object followed by the method.
    //however valdiate._p.list won't be accessible to the global scope    
    return {    
        check: function() {
              noDigits();
        },
        fnNaMe1:function(){
              _p.init();
        },
        fnName2:function(){
           return _p.list.slice(0);//return a clone  
        }
    };
})();
