> That's how the for-in loop works, no idea why. for in loops go backwards because they compile to reverse loops which are MUCH faster than forward loops. For more detailed information on this subject, check out the Flasm page.
http://flasm.sourceforge.net/#optas Here are the fastest loops: // Pre-decrement (--a) is faster than post-decrement (a--) // and subtraction (- (-1)) is faster than addition (+1) // This can be SECONDS faster than any for loop var a = 100; while (--a -(-1)) {} // Second fastest var a = 100; while (a--) {} // Here's the fastest for loop. Note the crazy syntax: for (var i = myArray.length; --i -(-1); ) {} _______________________________________________ [email protected] 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
