Summary: Extremely Informative for a Programmer
Review: This selection is fantastic. Of the books I've read on programming, this is probably the second best out of fifteen or sixteen. (The best is Deitel & Detiel "C++ How To Program")If you have experience with a C, C++, or Java type language, I highly recommend this title for learning Javascript. The pace starts quickly, the examples are excellent, and the reference section is complete.

Summary: a must have for javascript programmers
Review: If you want to learn JavaScript real quick and have a handy reference in the future then this book is what you're looking for. I am usually traveling to client sites so I have to choose wisely what books I will pack in the suitcase. This is definitely one of the books.

Summary: Good resource/reference
Review: This book, along with Dynamic HTML by Danny Goodman, provided me with a good learning tool and reference on Javascript. The organization and style is concise; the details you need are included. What I didn't find in one was usually found in the other.

Summary: Great book.
Review: This is a great book for professional programmers. The beginning gives the stuff that seasoned developers look for - a definitive reference on the core of the language. This is good because it allows one to identify where various implementations of the language deviate from the standard. The remainder of the book is done in the familiar O'Reilly style - consistently organized, thorough, informative. If you're looking for entertaining reading, don't look here. If you're looking for a reliable reference on JavaScript this is it.

Summary: Interesting
Review: I have read this book in one day. That was possible because most (but not all) of the book is extremely easy to read, giving exactly the information you need, no more, no less. I knew very little about JavaScript in the morning. Now I know all about it :) But there are parts of the book I'm dissatisfied with. Reference part (which takes 50% of the book volume) is very inconvenient to use. It is more like index: an unstructured one-dimensional flow of alphabetically-ordered texts. I feel that a couple of upper structure levels are needed in the reference. Presently, you can only find a thing if you know its exact name or you perform full-scan of the reference. Discussion about object-oriented ideas in JavaScript is also frustrating: I just cannot understand. It looks like this chapter is written by entirely different person, because it contradicts the clear style of the rest of the book so much. My summary is: <SCRIPT language="JavaScript"> if(you.needToLearn("JavaScript")=="quick") grab.thisBook; </SCRIPT>

Summary: Very Instructional
Review: I keep several books for programming in JavaScript. This was not the first book that I purchased, but will probably be the last. I keep coming back to this book for information. The author clearly knows JavaScript and puts it in plain english. I turn to this book now on every occasion that I need reference material. I have also learned some things from this book that I ws not aware JavaScript could do. I work on a web team and now everyone on the team has a copy of this book. It is a GREAT investment.

Summary: One complete source
Review: If i needed to choose just one JavaScript book to use as a reference and as a guide this would definitely be it. The book is complete very accurate and very through.

Summary: Not for beginners? Darn straight! Great book
Review: Another reviewer criticizes this book as not being for beginners. I say, thank goodness! This book is tailored as a stripped down, exhaustive guide to JavaScript in two parts: one by area of utility, another by function. This is the book I turn to when I need to write code, as it has everything I need in it. It's absolutely not for beginners, and, you know what? Some books can't be. This is for people fully comfortable with JavaScript who need a reference because they haven't memorized the five thousand items in the language and all permutations and interactions. Which is most of us, right? I write JavaScript every few weeks, not daily, and I love this title. I buy each new one when it comes out. (Which might mean this book is at the end of its revision schedule because when will a new JavaScript version ship? Probably never.)

Summary: Not For Beginners!
Review: Luckily I already had a solid handle on the basics of JavaScript before reading this book, because otherwise I'd be lost. One of the things every beginner programmer books needs is real-word examples of code with an explanation for almost EVERY line containing something new. It sounds excessive, but if you want to learn something, that's how it works. This book, for example, seems to have devoted half a page to the built in Date() function - which is ridiculous! Dates in JavaScript are a big deal to me, and something I want to learn a lot about. Ironically, the accompanying pocket reference that I happened to buy along with this book had more information concerning dates than the book, and answered the questions I had at the time, albeit with some guesswork on my part. The only thing I will praise this book on for now (still going through it) is its chapter on the DOM - Document Object Model. So far it seems quite plentiful, which is good. I'm no JS buff, but it seems as if the DOM is a major part of the language. Bottom line: do not buy this book if you're new to programming. If you already have a handle on variables, functions, arrays, and other such things, then you might be able to make do.

Summary: Great JavaScript Book!
Review: This book is by far one of the best books I have ever seen on JavaScript. I have some experience in C++, and after reading the introductory chapters, I noticed that its syntax is very similar to that of C++. I can honestly say that I now know JavaScript. Its index is great too. Anything that I needed to find, I found in under 5 min. Ok, that's a rough estimate. It's not like I was clocking myself everytime I looked something up, but you get the idea. I highly recommend this book to anyone who needs/wants to learn JavaScript.
