Today’s article follows up on last week’s article that began by running many of the performance tests on this site with the newly-released Flash Player 10.2. Last week I got through half of the performance tests I did in my Flash Player 10.1 followup (see part 1, 2, 3, 4, 5, 6) and today I’ll cover the second half. What faster and what’s slower in Flash Player 10.2? Read on for a ton of performance test updates!

From a performance perspective, lots changed in Flash 10.1 (see part 1, 2, 3, 4, 5, 6). Flash Player 10.2 was officially released last week, so it’s time to update this site’s many performance tests to the new player. This time around I’ll be updating more performance tests per part of this series, so hopefully everything will be updated a lot quicker than last time. Read on for the updates!
Why do I see so many AS3 programmers writing so much redundant code? Are you one of them? Today’s tips may save you a lot of typing. It may even save you a lot of SWF size.
Today’s article follows up on an article I wrote way back in August of 2009 about the order of operations when you use a class. In the original article I showed the order of field initializers and constructors. Today I’m expanding on that to show three more chunks of code that are run. Can you guess what those chunks are?
One of AS3’s strong suits is its ability to very easily use classes in a dynamic way. Every once in a while, this leads MXMLC to completely remove some of your classes from the output SWF and you then get some very strange behavior. Read on for some strategies for using dynamic classes without going insane.
Today’s article is a followup to an article (Cast Speed, itself a followup to Two Types of Casts) from September that continues to gather comments. Sharp-eyed reader fastas3 brought up a good point that warranted some further investigation into the topic. So today we’ll be taking yet-another look at typecasting in AS3 to try to unravel some of its strange mysteries.
I’ve talked about var args, the arguments keyword, and even the length of a function that has default arguments, but I’ve never written an article all about default arguments… until today.
Today I’m revisiting an article I wrote last August about conditionals: if-else chains, ternary (? :) operators, and switch statements. In that article I showed that if-else chains are about as fast as ternary operators and that both of them are 10-15% faster than switch statements. Today we’ll take a look at how those conditionals scale beyond just the few cases in the last article.
I wrote an article last November titled For Vs. While that needs a bit of updating an expanding today. While I updated the performance figures in my series on Flash 10.1 performance, I continue to get questions in the comments section of the original article that explore new areas. So today we’ll look at the ubiquitous for and while loops a little more.
I wrote an article in November 2009 titled Faster isNaN() and a followup to it titled Even Faster isNaN() and continue to get comments on both, so today I’m doing a followup to bring together both articles and the many comments on them into one definitive article. (UPDATE: added Windows performance results)
