Random array in AS2 & AS3 example using sort

I suppose many of you know how to use sort to get random array…
For those who are not familiar with those nice feature of sort method I will explain the idea. Sort method can randomize array if you put function that return -1, 0 or 1 randomly, which basiclly tells sort randomly are elements less then, equal or greater then eash other.

AS2 Random Array based on Sort source:

var a:Array = new Array(“a”, “b”, “c”, “d”, “e”);
function shuffle(a,b):Number {
var num : Number = Math.round(Math.random()*2)-1;
return num;
}
var b:Array = a.sort(shuffle);
trace(b);

AS2 Random Array based on Sort source:

var a:Array = new Array(“a”, “b”, “c”, “d”, “e”);
function shuffle(a,b):int {
var num : int = Math.round(Math.random()*2)-1;
return num;
}
var b:Array = a.sort(shuffle);
trace(b);

EDIT: you can take a look at algo comparison, with source for much faster approach in new post
