AS3 has three kinds of loops—for, for-in, and for-each—but which is fastest? I attempted to answer that question about three years ago, but the article is in dire need of a followup as many version of Flash Player have been released since then and the question is core to our everyday lives as AS3 programmers. So which type of loop is fastest in 2012?

Loops With int and uint
Jun 20
AS3 has two integer types: int and uint. In my experience, most AS3 programmers just use int everywhere and ignore uint. This is usually acceptable as the need for unsigned integers is rare compared to their signed counterparts. However, there are significant performance differences between the two. Read on for the impact of uint on your loops. The original version of this article’s performance test contained a small-but-critical error that led to a lot of incorrect analysis and results. This version of the article has been corrected.
For Vs. While Revisited
Dec 27
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.
For Vs. While

I’ve recently been seeing more and more usage of while loops by those who I presume are interested in performance. I’ve always assumed that these was not faster than for loops, but today I am finding out.
