JS 工具类

之前工作用的JavaScript比较多，总结了一下工具类，和大家分享一下，有不足之处还请多多见谅！！

1. 数组工具类（arrayUtils）

    //arguments parameter
    object.concat = function (arr) {
        if (arguments.length > 0) {
            for (i = 1;i < arguments.length; i++) {
                arr=arr.concat(arguments[i]);
            }
        }
        return arr;
    };
    object.join = function (arr,separator) {
        return arr.join(separator);
    };
    object.push = function (arr) {
        if (arguments.length > 0) {
            for (i = 1;i < arguments.length; i++) {
                arr.push(arguments[i]);
            }
        }
        return arr;
    };

        return arr.slice(start,end);
    };
    object.sort = function (arr,isDesc) {
         if(isDesc){
             arr.sort(function (a,b) {
                 return a<b?1:-1;
             });
         }else{
             arr.sort(function (a,b) {
                 return a<b?-1:1;
             });
         }

    };
    object.unshift = function (arr) {
        if (arguments.length > 0) {
