Version 3 has all characteristics of any serious programming language. Version 2 was somehow a scripting language targeted at unexperienced programmers. That specification also forms the chore of the Javascript 2.0 language contributed by the Mozilla foundation (see tamarin project at ).ĪctionScript 3.0 is an object-oriented language for creating applications and media-content that can then be played back in Flash client runtimes (typically the Adobe Flash Player, more recently the AIR framework).įor those already familiar with a Flash authoring environment, it needs to be mentioned that quite important changes have been introduced in the ActionScript language between version 2 and version 3.

For the moment, two authoring environment are covered in this wiki, Adobe Flash CS3 and Adobe Flex. This pages is for actionscript concepts that apply to any ActionScript 3.0 authoring environment and any runtime that supports ActionScript 3.0.
