how to randomize an array

1function randomArrayShuffle(array) {
2  var currentIndex = array.length, temporaryValue, randomIndex;
3  while (0 !== currentIndex) {
4    randomIndex = Math.floor(Math.random() * currentIndex);
5    currentIndex -= 1;
6    temporaryValue = array[currentIndex];
7    array[currentIndex] = array[randomIndex];
8    array[randomIndex] = temporaryValue;
9  }
10  return array;
11}
12var alphabet=["a","b","c","d","e"];
13randomArrayShuffle(alphabet); 
14//alphabet is now shuffled randomly = ["d", "c", "b", "e", "a"]
