ActionScript 3.0 is a huge upgrade to Flash's programming language. The enhancements to ActionScript's performance, feature set, ease of use, cleanliness, and sophistication are considerable. Essential ActionScript 3.0 focuses on the core language and object-oriented programming, along with the Flash Player API. Essential ActionScript has become the #1 resource for the Flash and ActionScript development community, and the reason is the author, Colin Moock. Many people even refer to it simply as "The Colin Moock book."
And for good reason: No one is better at turning ActionScript inside out, learning its nuances and capabilities, and then explaining everything in such an accessible way. Colin Moock is not just a talented programmer and technologist; he's also a gifted teacher.
Essential ActionScript 3.0 is a radically overhauled update to Essential ActionScript 2.0. True to its roots, the book once again focuses on the core language and object-oriented programming, but also adds a deep look at the centerpiece of Flash Player's new API: display programming. Enjoy hundreds of brand new pages covering exciting new language features, such as the DOM-based event architecture, E4X, and namespaces--all brimming with real-world sample code.
The ActionScript 3.0 revolution is here, and Essential ActionScript 3.0's steady hand is waiting to guide you through it.

I think it is important to state that this book is in NO WAY aimed or intended for beginners. None of the books in this series are, for that matter. Being fair, and I think this information is important for people even though a bit off topic: O'Reilly RARELY makes beginner level books. What they do make is insanely useful technical books which will tell you more than you probably ever wanted to know about a subject. But they are done, IMHO, very well. Still, when looking at books to buy I think it is important to keep this in mind, particularly if you are a beginner in any topic. Especially because most programming books are rather spendy.
When I bought Moock's first book, I had been using AS for a couple years (starting from Flash 4) and was still a beginner. However, I could manage my way through the very limited scripting options. When Flash 5 opened up the AS language to a full-blown environment, I was excited to get his book. Once it arrived, I was completely overwhelmed and immediately put it away. For about a year. During that time, I found other materials and boned up on my AS, THEN revisited the book. I found it much more useful.
When AS 2 came out, I thought the same thing. Ah-ha! I already know AS, so his book will get me up to speed. Wrong. The stuff which was pretty much lifted from the previous AS 1 book made sense, but I could not grasp what he was saying about the updates and new features in AS 2. Again, I put the book away for a year, found other resources to familiarize myself with, and revisited the book. I was surprised at the wealth of information I learned, but I learned it AFTER reading numerous other sources.
Leading to this book, I completely expect the same. I am buying it because I KNOW it will be a tome well worth the price based on my looking through it at local book sellers. No one, at least that I have read, has the depth of understanding of AS Moock does. He, IMHO, really understands the what and how. And he will tell you EVERYTHING about it. He does not, sadly, possess the 'layman language' to make this a beginner book. It barely makes sense to those well immersed in the topic. BUT, once you get to the level that you can absorb what he is saying, you catapult your Flash skills and usage.
For beginners, definitely start elsewhere. Books by Phillip Kerman or Joey Lott are marvelous entry level books. Both authors have a superior knowledge of Flash AS, but the also possess the ability to talk about it conversationally. A huge help in anyone's learning of a new subject. Flash AS is a huge uphill battle, but one which rewards richly for those who travel the path. I would just hate to have someone not try because they do not understand a book reportedly aimed at developers with 'no prior programming knowledge.'
Where I also have a problem with this book is how it instructs. I've been able to follow along with the coding but the author's explanation and instruction are lacking. Its obvious that he is very knowledgeable but he doesn't do a good job of passing that knowledge on. He's all over the place, explaining some things in depth, but not touching on other things you'll have questions about. At times it will feel like he is totally scatter-brained or ADD because he'll be going on about something inconsequential, while ignoring something else that you really want the answer to. Despite it being 900+ pages, I've had to go online to find answers to fill holes in his teaching. But also it feels at times like he's trying to talk over your head and give you the official-to-the-letter-Help-menu definition. I know there's a better way to teach people this stuff, and I've read books that do that.
I give it 3 stars just for the shear quantity, and I appreciate the effort. I just wish this book was not only packed with information but also taught it well.
If you are a designer who simply wants to learn how to control animations in the Flash authoring tool, you probably don't need this book, and Adobe's documentation should be sufficient. Come back to this book when you want to learn how to add logic and programmatic behavior to your content. If you already have existing ActionScript experience, this book will help you fill in gaps in your knowledge, rethink important concepts in formal terms, and understand difficult subjects through plain language. This book is divided into three parts.
Part I, ActionScript From the Ground Up, provides exhaustive coverage of the core ActionScript language, covering object-oriented programming, classes, objects, variables, methods, functions, inheritance, datatypes, arrays, events, exceptions, scope, namespaces, and XML. Part I closes with a look at Flash Player's security architecture. This section consists of chapters 1 through 19.
Part II, Display and Interactivity, explores techniques for displaying content on screen and responding to input events. Topics covered include the Flash runtime display API, hierarchical event handling, mouse and keyboard interactivity, animation, vector graphics, bitmap graphics, text, and content loading operations. This section consists of chapters 20 through 28.
Part III, Applied ActionScript Topics, focuses on ActionScript code-production issues. Topics covered include combining ActionScript with assets created manually in the Flash authoring tool, using the Flex framework in Flex Builder 2, and creating a custom code library. This section consists of chapters 29 through 31.
This book closes with a walkthrough of a fully functional example program--a virtual zoo, the pieces of which have been discussed as examples in explanations of various aspects o ActionScript throughout the book up to this point. Noteworthy ActionScript-related topics that are not covered extensively in this book include MXML, the Flex framework, Flex Data Services, the Flash authoring tool's built-in components, Flash Media Server, Flash Remoting, and ActionScript's regular expression support. The detailed table of contents is as follows:

The great thing about this book is that besides covering the details of building a large scale application, it doesn't ignor small things like "With what do I compile an ActionScript program?", "What tools do I need?", "After I compile an ActionScript program, what exactly do I have?" Plenty of example code is shown throughout and the explanations are clearly written, so you shouldn't get lost if you read the book through sequentially. Highly recommended.
With this third edition, "Essential ActionScript" has evolved into THE authoritative ActionScript resource. As one indication, this edition as over 900 pages while the last edition had about 500. There are over 15 technical reviewers, including chief Adobe engineers. This book is the one you want.
This concrete approach is something most of us will appreciate.
These are the topics discussed in Chapter 1 alone (after a 14 page preface that will leave you gasping for breath!): Runtime Environments, Compilation, Just-in-time Compilation, Classes, Objects, Packages, Access Control Modifiers for Classes, Constructor Methods, Variables and Values, Constructor Parameters and Arguments, Expressions, Instance Methods, Method Parameters and Arguments, Method Return Values, Method Signatures, Members and Properties.
And those are just *some* of the large bold sub headings in Chapter 1!
I repeat: THAT'S CHAPTER ONE ONLY. 43 pages of absolute gibberish if you are a beginner. Not to mention that the author is using ridiculously complex language. He tries to give the impression that he is properly explaining himself to new programmers, but he hasn't got a clue how to speak to beginners. For example, on page 9 he explains what the word "character" means (?). Everyone that has ever owned any device that has a keyboard knows what a "character" is! Yet on the same page, he uses the word "delimit" without a hint of an explanation. I know what delimit means; I've been coding websites for 7 years. But is he sure that a beginner knows?
While I did not yet officially read past the 1st chapter (I'm planning on reading ch.1 about 14 times before I move on!), I did flip through all 900 pages, trying to find something that I might actually be able to use in a Flash Application sometime soon. I didn't even come close to finding ANYTHING that wouldn't require hours and hours of study, practice, and debugging.
Here's another example of the book's off-the-wall structure: On page 579 he states that "ActionScript code cannot be included within an <A> tag's HREF attribute". He's supposedly speaking to people with "no prior programming knowledge" and he waits almost 600 pages to tell us that? And yet chapter one discussed all the things I mentioned above?
An explanation for why the book does not speak well to beginners is implicitly provided in the preface -- the book was reviewed by a number of super-expert Flash architects and geniuses from within Adobe. We're talking about "Computer Scientists" and "Senior Engineers". How about getting someone with "no prior programming knowledge" to review it? I think that would have helped a lot.
And why on earth is the official Amazon title for this book "Essential ActionScript 3.0 ILLUSTRATED"? Illustrated? There are virtually NO ILLUSTRATIONS in this book! Virtually NO DIAGRAMS. Virtually NO SCREEN SHOTS of anything. It's just super-complex code.
I believe, as I said, that the mention *early on* that the book is good for beginners is nothing but a marketing ploy to pull in a few thousand extra books. I am writing this review in hopes of stopping beginners from wasting their money. If you want to learn some basic ActionScript that you can use *immediately*, buy "Sams Teach Yourself Flash MX ActionScript" by Gary Rosenzweig. He speaks to beginners and experienced programmers superbly (as do all of Sams authors). Even though Gary's book is slightly out of date, it's a much better investment if you are a beginner. Move to Colin Moock's much later, if ever, or else practice your ActionScript now and wait for the 4th edition.
Having said all of the above, I will add a positive paragraph about Colin Moock and this book:
Every experienced Flash developer and/or programmer should own a copy of this book or a previous version by Moock. Moock knows his stuff and has excellent attention to detail (unstructured though it is). This book is a raw ActionScript tome that will gradually turn an experienced coder into a superb ActionScript application developer.
To summarize: The book's marketing is deceptive; it's not for beginners, and even experienced developers will need to spend countless hours studying it to benefit from it.
