The real beauty? As you move ahead with the subset of JavaScript that this book presents, you'll also sidestep the need to unlearn all the bad parts. Of course, if you want to find out more about the bad parts and how to use them badly, simply consult any other JavaScript book. With JavaScript: The Good Parts, you'll discover a beautiful, elegant, lightweight and highlyexpressive language that lets you create effective code, whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web, this book is an absolute must.

Average Customer Rating:

Underwhelming

Customer Rating:

There just isn't enough unique content in this book for it to stand alone and be sold at the book's cover price. To be fair, there's some good content in the book (some), but just not enough to be worthwhile. This entire book could've been a series of blog entries, or perhaps a section in an updated edition of the Rhino book. I wouldn't recommend buying this book. However, if you're intent on getting a copy, look for used copies or copies at bargain prices (less than $10).

A good book	Customer Rating:
It is easy to write bad code in javascript. This book helps you to avoid potential pitfalls and write clean and structured code.

Not much there	Customer Rating:
I was very disapppointed in this book. For the price of the book there was very little content. I am returning this book and buying something with more substance.

Second best book on JavaScript

Customer Rating:

This is an excellent book, as it concisely illustrates a number of details that would be impossible to find in other books. Moderate/advanced JavaScript programmers will gain the most from this book, it is not particularly geared towards the beginner. The book has a very specific focus, so do not be deceived into thinking this book covers the entire language. For information like that, Flanagan's JavaScript The Definitive Guide will be better. This book, however, is an excellent discussion of the important features of the language. Highly recommended.

Quality that I expect from O'Reilly

Customer Rating:

This is a book that you can easily read in one sitting. It will run you through parts of JavaScript commonly considered "advanced" and help you become a better JavaScript programmer. Unlike other books on JavaScript which seem interested on pretending JavaScript is a weak and dysfunctional cousin of Java, it embraces the JavaScript object model and teaches you to use it correctly. I would strongly recommend anyone who intends to write JavaScript code read this book.
