AS3 (VM2) versus JavaScript – performance

Back in 2004, I was comparing loop performance in AS2 – for, while, and do while. That expanded to testing the same against JavaScript. The upshot (!) was that do-while and while were the fastest, and pretty close to each other, and much faster than for, in both JS and AS2. More surprising to me […]

Object Iteration in AS3 *is* random

A little-known fact about AS3 is that object iteration occurs randomly (“little-known” apparently to even some Flash Player engineers, as evidenced in this thread at flashkit). This happens with both and for loops.


Even the above output is not predictable, and running the sample is likely to have different results.
