In AS3, you can create an Array can be created with special syntax: myArray = []. You can even fill the Array with values all in one go: myArray = [1,2,3,4,5]. This is a nice shorthand that saves some typing compared to using the constructor: myArray = new Array(1,2,3,4,5). But, which way is faster? Today we find out! UPDATE: added a third way of creating arrays

A comment posted before the Flash Player 10.1 series of articles asked about the performance differences between creating an object with o = new Object() and with o = {}. Below I’ll look into the generated bytecode for these two approaches and test their relative performance to see if either approach is faster than the other.
The differences between Vector and Array have been quite interesting since Vector was introduced in Flash Player 10. Until just recently I didn’t know that there was special syntax for declaring a Vector akin to Array's special a = [1,2,3,4,5] trick. This got me thinking about the various ways one can declare a Vector and, of course, how they’re implemented in bytecode and what the speed differences, if any, are. Read on for some nitty gritty about how you declare Vectors in AS3.
This article is sort of a follow-up to my article on Flexible Loop Syntax. This was reported to my by a coworker who spotted the anomaly. I guess he had done with if the same sort of thing that I had done with for. Read on for a little insight into how the comma operator interacts with the if statement.
You could probably do this in most languages and it might be hard to spot. See for yourself.
