 * modify the original.

 * @param {Function} comparator A sorting function
 * @param {Array} arr The list to sort
 * @return {Array} a new array with its elements sorted by the comparator function.
 * @example
 *
 *      var diff = function(a, b) { return a - b; };
 *      sort(diff, [4,2,7,5]); //=> [2, 4, 5, 7]
