Rating: - Hits the Spot for Quick Introduction to JavaScript
Some programmers look down on the Sams Teach Yourself series as beneath their level. I imagine that some professional chefs also look down on a ham sandwhich. However, sometimes a ham sandwhich with cheese on rye really hits the spot. The Sam Teach Yourself series of books provide a practical and efficient way to get introduced to a new topic.
The "Sams Teach Yourself JavaScript in 21 Days" is no exception. With the emergence of AJAX as a cutting edge way to provide rich web based ... Read More
Rating: - Egregious errors!
There are enough serious errors in this book to overshadow any positive attributes it may have. Things like on page 88 (first edition, May 2002) where the author confuses the modulus of a number with its absolute value: "The modulus of a number is the same as the number if the number is greater than zero. If the number is less than zero, then its modulus is the negation of the number - that is, the modulus of -5 is 5. The modulus is sometimes referred to as the absolute value of the number." ...

Rating: - Well written book
I'm very pleased with this book. It covers a large amount of JavaScript. However, like any other Sams Teach Yourself in 21 days series, this book will take you longer than 21 days to finish. The only complaint I have with this book is the lack of a JavaScript reference in the back. While it has one, it's not that large. Over all, if you want to learn JavaScript, buy this book. You can easily tell by how well written the book is that the author of this book is great JavaScript programmer.
Rating: - Doorstopper. Not worth it.
I thought this book was pretty good, when I first started. Because I was able to do a little something with Javascript and I've never even really tried a scripting or programming language before (I know HTML, buts thats just markup). But I put this book on the back burner after I learned what I wanted from Javascript (and really hit the wall after not being able to really use it much more after that). So I started learning Actionscript, where I saw more opportunites for its use. I got "Actionscript: ... Read More
Rating: - Great for beginners, too slow for experienced programmers
I found this book very useful, and I was able to learn JavaScript from it, although I didn't follow the book's tutorials sequentially.
The most important thing to note is that this book is not really suitable for an experienced programmer who wants to add JavaScript to the list of programming languages that he/she knows. If you already know several other programming languages then you'll find the pace of this book much too slow. There are too many simple examples and too much discussion of ... Read More
