Book description:
This hands-on introduction to design patterns is for experienced Flash developers ready to tackle sophisticated programming techniques with ActionScript 3.0. The book takes you through the process step by step, explaining how design patterns provide a clear road map for structuring code that actually makes OOP languages easier to use. Although this book is still in progress, you can get going on this technology through our Rough Cuts version, which gives you access to the manuscript as it evolves.
