Everything about Flash

The first thing that made me pause when working with Java is discovering that it doesn’t have event listeners – at least not in the sense that I’ve come to expect based on my ActionScript experience.

Multithreading support – the ability to run different blocks of code separately, in parallel – has always been a requested feature in the Flash/ActionScript community (and it’s, indeed, coming). But the reality is, due to the way the platform is designed, reasons to use concurrency in Flash are very rare. I’m sure some exist, but it’s not part of the tasks you normally have to program into a website or even a generic application.
