My archive doesn't go back to the original thread, but I found a
reference to it:
Array.prototype.shuffle = function() {
var i = this.length;
while (i) {
var p = random(i);
var t = this[--i];
this[i] = this[p];
this[p] = t;
}
}
That's the solution Fumio Nonaka and Tatsuo Kato came up with back in
the day. It was a classic, extensive discussion on the topic here,
from a very long time ago. I still remember following it, as a young
coder, watching how some of the greatest FlashCoders of the time
discussed what the fastest way of shuffling an array might be.
Ah, well. Those were the days...
