Thank the Programming Gods for Colin Moock,
This review is from: Essential ActionScript 2.0 (Paperback)This is the third Moock book I've read, and once again, cannot recommend it strongly enough.
As usual, he writes with a clean, readable style. Complex topics are made accesible via authoritative knowledge and clear examples.
The differences between ActionScript 1.0 (Flash MX Actionscript) and ActionScript 2.0 are explained. It's nice to know, and a little elss intimidating than I expected, that relatively little has changed with the language. His earlier work, the seminal "ActionScript for Flash MX: The Definitive Guide" is as indispensable as ever.
Moock explains that less has changed with the actual language than has changed with "how" one writes an ActionScript application.
He then explains Object Orient Programming as it relates to ActionScript 2.0 and provides a primer of best practices the budding (or established) programmer should follow.
The book concludes with sample applications highlight various design patterns.
After reading this masterpiece, you'll be less intimidated and more prepared to upgrade your coding efforts.
