Summary: This book (...)
Review: Do not buy this book!!!
i read the whole book and did the exercises, there is a of mistakes in it, even in the excercises. the book looks pretty good when you read the preface, however, when you read the content of it, you will lose your way. do not expect you can learn much from it.

Summary: Not bad...not good either!
Review: Each chapter starts out well. But, the author begins to lose his reader due to either his unclear explainations (talking in circles) or just missing a step or two with his statements. Also, I have found a couple errors in this book. For example, page 63 regarding 'Variable Scope' and page 67 (Questions section) #20 is incorrect. It's a ok book if you have a idea of object-oriented programming, but I advise this is not a good book for the absolute novice in programming!

Summary: Avoid this book
Review: I recently finished a web development course using this book for javascript. The book is poorly edited and full of various errors. I doubt that this is the fault of the author and blame Course Technology. My progam tends to use books from Course Technology and I find them all poorly edited.

Summary: Worked for me!
Review: I used this book for a web development class on JavaScript. I felt that it was a good book and overall I have little ill to say about it. The examples are well written and do a good job of reinforcing what you read in the chapter. You read a little then do an example, then read some more, then add to the example and so on. You don't need any Programming experience to use this book just a decent understanding of HTML.
The only criticism I could offer is that the editor should have used arrows when content is being continued on a new line for reasons of page space so that readers will know and understand (beginners can have trouble with this). It's a good book for learning the whole language from the ground up and for this reason it's worth the money. It's not an overnight crash course (if that is what you are looking for).

Summary: Very difficult to comprehend
Review: I was forced to buy this book as a textbook for my JavaScript class and looked forward to learning the language. The author seems to know what he's writing, but assumes that you do not need everything explained. There will be numerous examples instructing the reader to type lines of code to build short programs, but the author neglects to explain how each line is actually affecting the program. I went out and purchased "JavaScript for the World Wide Web, 4th Edition: Visual QuickStart Guide" and used it often when I needed further and better explaining of terms.

Summary: Much Better than Oreilly series or Javascript Bible
Review: I worked on databases and programming languages like C and PL/SQL. I bought the much acclaimed Javascript Definitive guide as well as Javascript Bible. If you try to learn Javascript from above books - "THE BURDEN IS ON YOU TO LEARN THE JAVASCRIPT " i.e., the authors don't really give good examples or decent explanations to explain the concepts clearly. But "Javascript comprehensive" book has very good examples and will walk you through every line and bottom line is " AUTHORS HAVE GONE TO GREAT LENGHTS AND DID TERRIFIC JOB IN MAKING OUR LEARNING PROCESS MUCH EASIER". I am really looking forward for books on XML from the same publishers. Keep it up !

Summary: Both Sides of the Story
Review: JavaScript Comprehensive by Don Gosselin is a great way to learn the rudiments of JavaScript. After surmounting the rudimentary subjects on JavaScript, it will slowly lead you to the the course's intricacies and will prepare and provide you the advancement skills you need to write your own complex scripts. The weaknesses of this book include lacking of further informative details to complement a very important concept at times. Furthermore, though comprehensive, it still lack that necessary effort to further simplify an easy task, but overall this book is a great reference and a great guide in achieving concrete grasp on JavaScript. I also recommend other Web Warrior books.

Summary: JavaScript-Comprehensive by Gosselin
Review: JavaScript is not a language, but a collection of regional dialects of C++ or Java. Having said that, Mr. Gosselin's book is extremely difficult to understand. One never knows if he is using an illustrative name or calling a builtin function in his examples. His inability to explain just what a JavaScript object is puts him at a distinct disadvantage, which is not helped by the errors and ambiguities with which he attempts to advance his book.
He also doesn't seem to have a clear idea of the relationship between HTML and JavaScript. There are many clearer authors and other comprehensive books. Readers would do well to leave this one on the shelf

Summary: JavaScript Comprehensive
Review: The first thing one notices about "JavaScript-Comprehensive" is that neither the publisher, Course Technology, nor the author, Don Gosselin, could come up with any reason for the reader to part with (the money) for this book. With good reason. Having read more than 300 pages, I am convinced that Mr. Gosselin is as lost as I am when it comes to JavaScript.
He seems to have no idea of what an object is, and is completely incapable of explaining how JavaScript and HTML meld into a single whole. On the otherhand, Professors Nakhimovsky and Myers, in "JavaScript Objects" have no trouble describing JavaScript objects as associative arrays, and pointing out that HTML governs how a web page looks and JavaScript controls how it behaves. Gosselin is at his most confusing when describing objects, functions and variables (is there anything else?). One never knows when he is using an illustrative name or a builtin function. The coinage of the term "instantiate" is annoying since he means "create an object" in some cases and "populate and existing object" in others. Mr. Gosselin may be able to explain how to use office applications, but he should leave JavaScript alone.
