ActionScript 3.0 is the new version of the Flash scripting language, and with it comes a lot of new things to learn. In addition, you can also make use of it through Flash CS3, through Flex 2 and 3, or even through open source tools.

Fortunately, we've created this book to teach this new language to both aspiring ActionScript developers, and experienced ActionScript developers who want to upgrade their knowledge to the new version. It doesn't aim to be an exhaustive reference, focusing on essential real world techniques to enable them to get up and running quicker. In addition, we cover how to use ActionScript 3.0 through both Flash CS3 and Flex 2/3 (open source ActionScript developers should also be able to make use of the book.)

As well as countless practical examples, reference sections are also included at the back of the book allowing the reader to easily look up syntax.

No previous ActionScript knowledge is assumed, although it would be beneficial.
