Sams Teach Yourself JavaScript in 21 Days

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.

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 basic programming principles.For a beginning programmer these many examples and down-to-earth discussions are great. The authors assume that the reader has no knowledge of programming at all, which is fine if the reader is new to programming.A couple of the especially useful things I found in this book were an example showing a clever way of using the onClick event for an "a" tag, and information about where to find the Microsoft script debugger.On the other hand, I did find a few minor errors. And on page 20 a CD-ROM is mentioned, but in fact no CD-ROM accompanies the book. Instead, as explained on page 5, the sample files from the book are available on the Internet.So if you're new to programming then this is a good book for you, but if you're an experienced programmer then you should find something else.Rennie Petersen

This is the book that I used to teach myself Javascript.I was able to breeze through it in 3 days, not 21 days and I would recommend the Teach Yourself series by SAMS to anyone who wants to learn a computer language.Later when you need a big reference book, I would recommend "JavaScript: The Definitive Guide" by O'Reilly.

I like the fact that its very beginner friendly. I tried reading the O'riely book and it was talking about topics I wasnt ready to cover yet and it was boring. I mean they spent a paragraph on each topic and didnt have many fully coded examples just a whole bunch of snippets without showing how it would look on screen. So I switched back to this book. It explains things for the beginner. If you are new to JavaScript this is a good book for you to get started with.

I'm in a somewhat unusual position, in that I've needed to work on some rather advanced JavaScript scripts without really learning the fundamentals. I've struggled through my projects using Danny Goldman's JavaScript Bible and many online resources, but there are holes in my knowledge that you could drive a truck through.While Goldman's JavaScript Bible is an excellent reference book, I quickly grew frustrated when I attempted to work my way through it as a tutorial. I wanted a book that was designed as a tutorial, and used simple language to teach complicated subjects. I picked up "Teach Yourself JavaScript in 21 Days", and unlike Goldman's book, it uses simple language and a simple structure to give a clear picture of JavaScript.I do spend well over the suggested time on each chapter, doing all of the exercises and modifying them in whatever ways I can think of. As a result, many of the things that have perplexed me for months are becoming second nature, and I'm seeing improvements in my coding abilities daily. And I'm only on chapter 4!Perhaps my pre-existing knowledge of JavaScript is why this book seems so intuitive to me, but whatever the reason, I am excited to pick up "Teach Yourself JavaScript in 21 Days" every morning. My fundamental grasp of JavaScript has improved dramatically, and I absolutely feel this is the best tutorial book I have purchased.
