Summary
This hands-on introduction to design patterns is for experienced Flash developers ready to tackle sophisticated programming techniques with ActionScript 3.0. Now that ActionScript has been reengineered from top to bottom as a true object-oriented programming (OOP) language, reusable design patterns are an ideal way to solve common problems in Flash applications. But learning ActionScript 3.0 is a challenge for anyone without adding this extra learning curve. ActionScript 3.0 Design Patterns takes you step by step through the process, first by explaining how design patterns provide a clear road map for structuring code that actually makes OOP languages easier to learn and use. You will then learn about various types of design patterns and construct small abstract examples before trying your hand at building full-fledged working applications outlined in the book.
