A must have for beginner Javascript Programmers
If you want to have sophisticated webpages without using Net Framework 2 or 3, then this book is a must. I highly recommend it.
Nicely done, but not the best
Mastering Javascript is an excellent book for a newcomer to JavaScript, but I find that its value for updating my previous knowledge of JavaScript was much less than I expected. The book is a hefty 1100+ pages, and they avoid providing beginner's information on HTML, thankfully. Yet the language in the book is somewhat dry, even considering normal standards of writing in similar style books.The book is good for those who already have a background in programming, and are interested in venturing into JavaScript. There are extended JavaScript examples in the book, and sample code is provided on a companion CD.
A very appreciated section on XML is included, and this was the section I focused on the most. Yet it doesn't develop it as much as I would have expected it to, considering how much it had already done with previous topics.
All in all, I would have enjoyed it more if this had been my first introduction to JavaScript. As is, it is still a good ride, though not as satisfying the second time around.
Completely useless as a reference
I bought this book as a complete reference to the javascript/jscript language. Instead I got a much to broad beginner's guide. The index is lousy, which makes it even worse as a reference, and server side javascript is mostly ignored.
If you want a javascript beginner's guides, sure you can go for this one, but it is definitely not for advanced programmers, it hasn't helped me solve one single problem.
Not for advanced JavaScripters
This book does not cover the details of most of the Javascript objects. The examples are good enough for beginners who are just getting to know javascript.
Easy to follow, infomative - Recomended
I'm about half way through the book and I find that is very informative, easy to follow. The one think I don't like is that it is focused on older browser development for Navigator 3. But I would definetly recomend this book to others.
