Summary: Lacks a good index
Review: A very good reference if you are good in the basic concepts of C++ / Java or if you already program using Javascript. This pocket book should stay close to your computer. After a sufficient practice of Javascript programming you won't need another guide.

Summary: lots of code in a little package
Review: A very nice little book with lots of code. Being relatively new to javascript, though, I found it to be a little bit too concise. Why? The descriptions of each part of the syntax were too short. Still, if you know javascript, this book is very worth the price.

Summary: For programmers who don't need fluff, just syntax.
Review: A very rare O'Reilly book that isn't well written (that's because there is no writing!) An utterly consise book with nothing other than the syntax and VERY brief descriptions programmers will understand immediately. Get it if you need to have that site up and running today.

Summary: This books rules!
Review: Anyone with a mind to program in JavaScript NEEDS this book. I really mean that. It does not waste any time explaining, it gets straight to the rules/syntax of this language. I rate it as top-notch. I lost my first copy so I'm ordering another one. That's how important I think it is.

Summary: near perfect, nothing better is currently available
Review: First off, I'd like to say that I find these pocket reference books absolutely indispensible. They're relatively inexpensive, they contain MOST (if not almost all) of what you need, and they save you the need to carry absolutely HUGE tomes when all you want is just to look something up quickly. If you know HTML and JavaScript, then get this (JavaScript) and the HTML quick references and you'll be able to do almost anything on your own. To nerds, pockets were invented for carrying such useful pocket guides.The JavaScript pocket ref continues the tradition of indispensible pocket references by O'Reilly. The organisation is good, and the book contains examples and explanations that you wouldn't expect to see in a pocket reference. Amazingly though, there's no treatment of objects and object oriented programming in JavaScript. Most readers can be expected to know this, but if you're used to programming in C++ and Java, and don't do a lot of JavaScript, it's easy to forget. I think all the missing material on objects could be treated in ONE MORE PAGE. (hint for next edition!) Otherwise, this is a wonderful book.

Summary: Lacks a good index
Review: I bought this book because of all the good reviews posted. Unfortunately, I cannot agree. As a good reference tool, I expect it to have at least a good index. So that when I am coding and forget the exact syntax, I can quickly find it. Unfortunately I can't use this book for this purpose. I keep on having to go back to the bulky JavaScript Bible, which has an excellent index. This book simply does not serve the purpose for me. What good is a concise reference if I can not quickly locate the info I want?

Summary: just not meaty enough
Review: I use it on occasion to refresh my memory about an attribute name or a method, but I usually have to go to the big books to get any more help than that. It's skimpy.

Summary: If you've already got the "Definitive Guide", skip this
Review: I was hoping and expecting that this little book would be the same quick-and-easy reference book that e.g. the "VBScript Pocket Reference" is -- I was sadly disappointed. Since "JavaScript: The Definitive Guide" is by the same author and publisher, I also expected this book to be a (somewhat) boiled-down version of the very thorough JavaScript Reference from that much larger book. I was even more disappointed there. In a "pocket reference" such as this I want and need nothing more or less than an alphabetical listing of the JavaScript universe. However, this book is divided into numerous chapters that require you to already know what category the thing you seek belongs to. Since there's no index in these little books, it is useless to me as someone who's still learning this stuff. I've set my copy aside and use the "Definitive Guide" exclusively.
