ActionScript 3: Shuffle/randomize any Array

A quick little function for randomizing/shuffling an Array that contains objects or primitive of any data type:

public static function randomizeArray( arr:Array ):void
{
 for( var i:int = 0; i < arr.length; i++ )
 {
  var tmp:* = arr[i];
  var randomIndex:int = Math.round( Math.random() * ( arr.length - 1 ) );
  arr[i] = arr[randomIndex];
  arr[randomIndex] = tmp;
 }
}

You can see that it crawls through an Array, swapping each position with another, random position in the Array.
