var Match = (function(){
    var arr = null;
    var len = 0;
    return {
        max:function(arr,len){
            arr = arr;
            len = arr.length;
            var newArr = arr.sort();
            return newArr[len-1];
        }
    }
})();
var maxCount = Match.max([3,4,5,11,3,4,55,67,88,33]);
console.log(maxCount);//88
