Editorial Reviews

From Barnes & Noble
The Barnes & Noble Review
Whether JavaScript is your first language or your tenth, whether you’re building web doodads or e-commerce applications, this systematic, disciplined course will help you master the language with remarkable efficiency. And with some of the more egregious browser incompatibilities fading into memory, now’s a great time to learn JavaScript -- or to go beyond “snippet-stealing” to build real new functionality of your own.

Updated through version 1.5, Sams Teach Yourself JavaScript in 21 Days consists of 21 neatly organized one-hour lessons, plus a handy function reference. In the first several lessons, you’ll how to work with data, functions, statements, arrays, and JavaScript objects -- especially the Number and Math objects, and the String object, designed for capturing data entered on HTML forms. Next, there are detailed lessons on browser compatibility and checking; date/time manipulation; event handling; debugging and error handling; and DHTML/CSS. You’ll also find an excellent introduction to regular expressions, which enable you to perform a truly incredible array of web tasks, from cleaning content to validating email addresses.

Part III leverages your skills in real application building, from cookies to shopping carts, password protection to on-the-fly graphics with SVG. By the time you’re done, you’ll have the confidence to try just about anything. (Bill Camarda)

    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 applications, the demand for a working knowledge of JavaScript will increase. 'Sams Teach Yourself JavaScript in 21 Days' goes step by step through the core aspects of JavaScript. This book teaches fundamentals such as variables, arrays, statements, functions, built-in methods, and basic objects. The book also teaches introductory DHTML and SVG manipulation--though some of it may seem out of date as the book was published three years ago. In general, the authors do a good job of explaining programming concepts and how JavaScript implements them. I found in a couple of cases where the code examples had errors. While I was able to work around the errors in the book, it's always frustrating when the example doesn't work. If you are a programmer who needs to implement JavaScript in your current project, 'Sams Teach Yourself JavaScript in 21 Days' will probably help you get up to speed quickly. Or if you are new to programming and need a step by step guide to a relatively easy language to use, you will find 'Sams Teach Yourself JavaScript in 21 Days' an easy to use and approachable book. If you are looking for a more advanced discussion of JavaScript, this book may disappoint you. You may want to consider O'Reilly's 'JavaScript: The Definitive Guide'.
