First off, thanks to everyone helping on this thread. I originally was using "object" == typeof(this[a]). Glad to see instanceof Array was fastest.
What I'm trying to do here is write new methods for Array (and next up is String) that other languages have but Flash does not. Some of these methods are extremely useful. This is why I'm injecting them right into Array with prototype for now. This is also why I'm trying to squeeze the absolute fastest performance out of these methods. The fastest loop in flash is not while (i--). Pre-decrementing is faster than Post-decrementing. while (--i -(-1)) is actually the fastest because of what it compiles to in bytecode. For more information on this and other cool optimizations, check out the Flasm page. One thing I'm wondering is if a decrementing loop and then a reverse() at the end is faster than an incrementing loop. I'm working on compacting Danny's script at the moment. -Steven _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
