"This is a very good book for the people who wish to make fancy personal web pages. This book grooms your Java Script concepts and also touches some nerves of of advanced scripting techniques. It is a good start for beginners and a very good refence book for the advanced users.In short, It's worth the price !" -B. Kataria, NY

I found this book very useful. I did not have the same difficulties as other reviewers.(I found no mistakes in the book,perhaps the earlier reviews alluded to problems that have since been corrected by the publisher)I loved the fact that there was no B.S, just what I needed to know.I was not an expert in Java but this book allowed me to get the training I needed without wasting my time. I would recommend it to users who do not have alot of time on their hands but need quick, competent training. I do not need the 'Java Bible' as another reviewer mentioned. I need to be able to do my job and quickly, this book helped me do that plain and simple- Samara Alman

This book is easy to read that is the only good thing about it.

If you are looking to use the examples in this book you will be sadly mistaken. The mirely don't work. In short a disappointment. If you buy this book don't be suprised if you want your money back. Part II is just as bad.

In you want a book that is easy to understand for all levels and scripting from the first day buy JavaScript Bible, It's excellent.

This book is Easy to read being how it only 145 pages. As far as Mastering Java Script you won't do it with this book. The big flaw in this book it THE EXAMPLE CODE DOES NOT WORK. If you are new to JavaScript and you don't yet have the knowledge to start debugging don't buy this book. If you want to buy a GOOD Book with examples that work thats tells you what browser they will work on buy the JavaSript Bible. You will be writing script from the first day with the JavaScript Bible, an Excellent Book and its 1000 pages of knowledge. If you buy Mastering JavaSript Part I or II you will be asking for you money back .. I PROMISE!

This book builds nicely through the basics. It's good enough that I'm going to buy the next course. One of the big problems, though, was that there are quite a few errors in their example code, but hey, I guess that's a good way to learn.

I am in the process of completing the reading of this book and found it easy and no-nonsense. I feel that the examples are also valuable since they focus on functionalities that many may want to use.

It's a very good book for begginers in JavaScript like me. I'm really learn much reading this simple and easy book.

This book is an excellent book for people who do not have experience in JavaScript. The examples are easy to follow and abundant. I liked it so much I went ahead and ordered the second in the series.
