Demo Code

Array.prototype.orderBy = function (property, compare) {
    var items = this;
    for (var i = 0; i < items.length - 1; i++) {
        for (var j = 0; j < items.length - 1 - i; j++) {
            if (isFirstGreaterThanSecond(items[j], items[j + 1])) {
                var temp = items[j + 1];
                items[j + 1] = items[j];
                items[j] = temp;/*from  w  w  w.  ja v a 2 s  . co m*/
            }
        }
    }
    function isFirstGreaterThanSecond(first, second) {
        if (compare != undefined) {
            return compare(first, second);
