Summary: AWESOME!
Review: If you are a beginner, think twice about this one. This is for the Pros. This book is seriously packed with improvements and deep explanations that you won't find anywhere else. With tons of pages and code samples to download covering everything you every wanted to know about web scripting with JavaScript. This is a definate keeper in your library!!...

Summary: It left me wanting
Review: If you have no or very little programming experience and are considering this book to learn from the ground up about JavaScript and what it is possible to do with it, I would recommend looking for something else. The first 100 pages describe the basic elements of the language (you know, the operators + - / % & == and the various control loops etc.) without, in my opinion, one worthwhile practical example of how these elements would be used in an actual application.An analogy that comes to mind would be that if a JavaScript program were a house, and I bought a book to describe what kind of houses I would be able to build, I would expect to see some examples of different kinds of architecture (simple whole programs) and step by step explanations of how those houses were built. This book describes the chemistry of mortar and the compression stresses on and of the bricks, and the characteristics of the various kinds of clay that the bricks where made from, and the different kinds of wood that could be used to frame a house, but I never really saw examples of houses, or of how to put a house together, at least, in a beginner friendly way. The book is titled Programmer to Programmer. Maybe that is where I went wrong. I have done some programming in C for WinXX, but I am not a professional programmer. I expected something more like Petzold's instruction. Instead I was left wanting.

Summary: Everything you wanted to learn on JavaScript is in the book
Review: Including the discussion on JScript.NET. Excellent coverage on JavaScript, providing practical solutions. A must to have book for every Web developer.

Summary: Should be half this size - very incoherent
Review: It really looks like production team was under orders to produce pre-set number of pages no matter what. Almost 300pg reference section would comfortably fit in 100pg and would be of some use then- after major rework, and reference is important part of a book calling itself professional. For example, no information on object method arguments is included, not even a list. Tables are at least twice as large then what would be reasonable for the content - almost like they went printing Web tables from and old browser. What was supposed to be Netscape and IE specific reference really looks like a verbatim copy of some web intro page. Proliferation of subtitles, many times just for one paragraph. Index with at least one level larger font size then what even Wrox itself used in ASP 3.0 book. Table of contents stretched out to 30 pages with big font sizes which rendered it almost useless. Way to many "buy this further Wrox book" nagging in the text up to a point where you have to start suspecting that not things are not present on purpose just to make you purchase one more. DHTML section is way too IE biased, even with no mention of some cross browser techniques you can see working on web. Client side JavaScript case study just goes presenting IE exclusive code, then some rambling how "Netscape can't do this" and then - a miracle - cross browser JavaScript library from the net :-) FI development of cross browser code was too much for authors they why not simply presenting several good libraries and explaining their inner workings? Authors of at least half chapters seem to be at loss about their intended audience. If this was written for web developer then one would expect to see things like events and document object model covered in one place and not scattered (as some tutorials have to do). I can't blame for this so much authors but project manager and editors (6 of them :-) Book with many authors scattered all over the planet lever or dies by good or bad project management to provide coherence. Chapters on server side, wsh and client configuration are fine but that is no more then several hundred pages. This book really needs major rework and split into two smaller volumes of which one would really be professional (with good reference section this time) and the other would be intro review volume. Then professional part would probably get 5 stars - and wouldn't break your wrist while you try to wade through to find something.

Summary: Oh boy, maybe if you never heard of JavaScript before...
Review: It's basically trying to put JavaScript everywhere without any details or real-life actions. All exemples are very briefly explained and have provides NO BONUSES to anyone that have at least a small experience of JavaScript. My goal when purchasing this book was to learn new tricks with JavaScript since I'm coming from VB and VBScript so I wanted to learn the special things about JavaScript. LOOK ELSEWHERE IN THAT CASE. BUT, if you are looking at WHAT IS JAVASCRIPT AND WHERE CAN I USE IT? it might be an 'okay' start.

Summary: I would recommend another book
Review: Numerous authors listed on the cover and you will see why when you read this book. Very fragmented book, several topics are covered twice. Not a very useful reference book. The only thing that saves this book from being having a rating of one were some of the examples (which I used on one of my projects), and I found a couple of chapters had some decent explanations. A better book is "Javascrip, The Definitive Guide by David Flanagan". I found this book to be much more helpful.

Summary: Index simply sucks
Review: OK, so I know this was not probably meant as a JavaScript reference. Then again, a good third of the book is reference appendices. These appendicies only go halfway -- they show the objects and their properties and methods, but not any of the syntax for invoking the methods. This makes the reference almost totally useless. That wouldn't be so bad if the index could point you to places in the text where these methods were explained in detail. However, this is the WORST index I've seen in any computer book. This book earns a 2 from me on the strnegth of Wrox's usual saavy tone and attention to detail in the text chapters, coupled with an unparalled depth covering emerging forms of server-side, embedded, and other forms of JavaScript. However, it would be THE ONE AND ONLY BOOK you'd need on the topic if only it had a damn index worthy of the name.

Summary: Amateur writing by intelligent hacks
Review: Ordinarily I'm a BIG fan of Wrox books, but this one let me down. Like many other reviewers, I was stopped too often by poor grammar, unintelligible sentences, and just plain wrong information. That this book ever made it to publication is an indictment of the Wrox editorial staff. Don't buy the book if you want to understand Javascript. In fact, don't buy it at all. I'm returning my copy (if I can).

Summary: Definately not a good How-To book
Review: Over all I think that the book is O.K. but, If you are a hard core programmer that wants straight to the point How-To material ,this is the wrong book. I found myself almost falling asleep on some of the wording. I am an experienced programmer that is moving my skill set to Internet programming.
