Makes the AS3 learning curve manageable,
This review is from: Essential ActionScript 3.0 (Paperback)
I knew flash and AS2 basics before picking up this book. It helped me cope with the incredibly steep learning curve that goes with the move to AS3.
Just take each page as it comes and stick with it, the penny will drop sooner or later and you'll have a very solid AS3 foundation. I'm now developing apps for ios and android with flash pro CS 5.5+ and this book.
