Summary: Good but could be better.
Review: This is a good introduction to JavaScript. I bought it in preferenceto the O'Reilly 'Javascript - The Definitive Reference' and to Danny Goodman's 'Javascript Bible', which, at the time were the only other serious books out there. If you want to learn DHTML you should get Danny Goodman's 'DHTML - The Definitive Reference'. Goodman's book is the DHTML bible but this Wrox book is better at Javascript. Yes, the Index and the continuity could be improved; the introduction to objects could be expanded with more and better examples; the regular expression section needs to be bigger. The case studies should have been dumped - they take up too much room, then the basics and reference could have been expanded. Unfortunately there really aren't any Javascript books which are significantly better. You must rely on web resources. Start with the Netscape site.

Summary: Lost of pages of nothing
Review: All I know is this book has many pages, but its one of those books where you can find everything except what you are looking for.

Summary: Needs Improvement
Review: And yes, another WROX. No formal organization, no definte goal, but a whole bunch of high class authors. The result: an excellent book if you're looking for examples of that little twist of class, a dash of luster code. There are excellent case studies that make this a good addition to your bookshelf and there are valuable hints scattered everywhere: but the total lack of organization and tutorial direction leaves the book like a box full of sharp tools hidden in a dusty attic. There is no attempt to teach Javascript (perhaps Paul Wilton's excellent Beginner Javascript is intended for that). The section on Good coding Practice is laughable: why does a book entitled *Profesional" Javascript have 2 chapters on programming practices? The Core javascript section is just a bare scratch on the surface of language itself and does not do Javascript any justice. The Jscript.Net seems to have been thrown in as an after thought. I like WROX for the "from the field" examples for which they are famous: and I found the case studies ( a third of the book) very interesting. However, sorry, Wrox, it's not worth paying that much for just the last chapters. I'll wait till it hits my library or wait for the 3rd edition.

Summary: Good but not great
Review: As a web developer, I've been using this book for the better part of a year now. That, coupled with the fact that it's getting a little worn, should be a testament to its overall usefulness. I haven't yet found a professional application for the advanced material presented -- I mainly work in DHTML -- but I like knowing that if I had to do server-side JavaScript, for instance, I could. However, the reference chapters -- always the most important part of a computer text -- are fairly useless. The IE DOM is hardly explained -- it could warrant a book of its own, but this book's sketchy outline is useless. The way the appendixes are laid out is inconsistent and not visual enough -- you have to dig for the information you need (for instance, which browser supports which core object). Finally, and worst of all, the methods reference doesn't give you any clue as to the parameters of the methods! I often find myself looking up the object description here, then going to MSDN to se what the parameters are. How silly. 3 of 5, because it *could* have been truly the only JavaScript book any serious programmer needs. As is, I'm off to the store to finally get a decent reference book. (Problem there is that all of them pre-date IE5. Where's the update, O'Reilly?)

Summary: great explainations
Review: Bryan Bertrand is right about anonymous reviewers! This is a great book! Lots of technical stuff explained clearly with a good dose of "when to" advice as well! I found it very clear in its explainations, especially in all the chapters that deal with Web browsers. Thats what I wanted. This book plus the O'Reilly one is all you need. If you've got big confidence problems, buy JavaScript Goodies first and come back for this book after trying a script or two. But I think most people can learn everything they need just from this book. 5 stars.

Summary: Excellant Case Studies
Review: Chapters 10 and 14 in this book are excellant case studies. The 'Family Tree Photo Album' is a great real-life example of how to use JavaScript practically and ties up what has been taught in the book. But then chapter 14 which is "Building an e-commerce shop front" goes beyond that to create a functioning online shop. It's brilliant! I have "borrowed" it for our company site. Thanks Wrox, this book surpasses even ASP2.0 in quality and depth. Keep up the good work.

Summary: Not for beginners!
Review: Code examples are very poor and lack adequate explanation. Code on page 22 uses "Clib.puts()" . The only explanation is "Our Example uses Clib.puts() to output to the screen- a call that's only made only on the server-side or most likely for running in a standalone JavaScript interpreter." What does this mean and what would be a good example with a useful purpose? Another example comes in the description of "Comma Operator". "What it does is evaluate its left value, throw the result away, evaluate its right value and pass that on. ... it allows you to put in your own side effects .." No explanation is made about throwing away the left value and there is no explanation about "side effects" what they are and when you or how you might use them. Sorry, but its another book for me.

Summary: A wealth of information - can't go wrong!
Review: Covers Javascript inside and out! If you started out with a QuickStart guide or Beginning series you have no idea what you are missing. What a powerful and enlightening book. Quick review to start and then dives into the good stuff! Thanks WROX! You did it again!

Summary: Java Script Professional
Review: Good book but was disappointed because it did not provide more details and examples of using CGI/Perl with Java Script. Seemed to be promoting the sale of ScriptEase Software.
