Though he does not cover server-side APIs, Flanagan has chosen to separate coverage of core JavaScript (all the keywords, general syntax and utility objects such as Array) from coverage of client-side JavaScript, which includes objects, such as History and Event, that have to do with Web browsers and users' interactions with them. This approach makes this book useful to people using JavaScript for applications other than Web pages. By the way, the other classic JavaScript text--Danny Goodman's JavaScript Bible--isn't as current as this book, but it's still a fantastic (and perhaps somewhat more novice-friendly) guide to the JavaScript language and its capabilities. --David Wall

Topics covered: the JavaScript language (version 1.0 through version 1.5) and its relatives, JScript and ECMAScript, as well as the W3C DOM standards they're often used to manipulate. Tutorial sections show how to program in JavaScript, while reference sections summarise syntax and options while providing copious code examples.

Perhaps its me?

Customer Rating:

I have owned this book for some time and I can honestly say it is unique. This is the only manual I have encountered that has been consistent in its inability to answer any query i have. Admitedly I am a Javascript novice but that's why I purchased this manual in the first place to help me understand javascript. The internet has quickly answered all my queries with ease and clarity, I really don't understand why this massive book is unable to do the same. As I said above it's probably me, as you can see there are many glowing reports for this book. In my defense I have been involved in the IT world for many years and have relied on manuals to help successfully resolve issues. This book continues to remain a mystery to me and I am seriously thinking of banishing it to the great library in the sky.

Definitive ? Absolutely

Customer Rating:

After many years struggling with rudimentary JavaScript and never being able to find a sensibly structured book on the subject, a colleague recommended 'JavaScript - the Definitive Guide'. O'Reilly have never really impressed me as a publishing house but this book is the best there is. The coverage is as extensive as it is complete. Especially noteworthy is its carefully documented chapters on the relationships between functions and objects which other authors shy away from. Want to be as good as Dean Edwards ? This is the book to get you there.

A needed update for an excellent guide

Customer Rating:

The 5th edition of the one and only bible of JavaScript, by the language guru David Flanagan, is not a surprise, but a beautiful confirmation. The 4th edition, which I've been using until a few days ago, was (and is) an invaluable reference even though it started to become a bit outdated. The new version is even more "biblic" than before, featuring nearly 1000 pages of in-depth explanation and reference. New sections include Ajax (of course, it's the cool thing of these years!), client side graphics (SVG, VML and ), JavaScript namespaces and communication with Flash and other embedded media. The book can be divided in 2 sections: the guide - which occupies about 600 pages - and the reference which accounts for the remaining 400. Browsing the index of the book, it turns out the the parts are actually 4: for this article, I however merged the first two (the guide) and the last two (the reference). The first section covers every JavaScript aspect, with a detailed explanation of the language and almost everything than can be achieved using it. What is being actually taught are the "roots" of all the JavaScript features: to build the complex things, you need to work on those roots (or to grab more high-level tutorials somewhere else). However, this book has everything you need, as you can figure the rest out! The second section is the reason why every web coder will want to have this book on his desk everyday. The reference is detailed, accurate, thorough and very easy to browse. As I wrote above, it's divided in 2 parts: Core Language and Client-side JavaScript. All in all, what can be said about this book? Even though I'm not fond of client side programming and prefer to script on the server, this is one of the few books for which I can really find nothing bad to say. It's well written, simple to understand, entertaining. There's also the Italian translation: there's the previous edition on the shelves in Italy at present time, but we'll hopefully see this new fantastic edition translated soon.

Can we have a review of the actual book?	Customer Rating:
I have the 4th edition of this book which is very good but out of date. Unfortunately so are the reviews, including the description provided by amazon all of which seem to apply to the 4th edition. So what is new in this Fifth edition? I am none the wiser as to whether this is worth the upgrade.

An excellent introduction and reference for Javascript	Customer Rating:
Probably the only Javascript book that you'll need for a long time. If you have programming experience and some understanding of object models then there should be almost nothing here that you won't understand and nothing outside of this book that you'll need. One of the best in the O'reilly series.
