JavaScript--the powerful, object-based scripting language that can be embedded directly into HTML pages--has earned its place in the web developer's toolkit, to the extent that it's now considered required knowledge for web developers. You can use JavaScript to create dynamic, interactive applications that run completely within a web browser. JavaScript is also the language of choice for developing Dynamic HTML content. Because its syntax is based on the popular programming languages C, C++, and Java, JavaScript is familiar and easy to learn for experienced programmers. At the same time, it's an interpreted scripting language, providing a flexible, forgiving programming environment for new programmers.TheJavaScript Pocket Reference, 2nd Edition, provides a complete overview of the core JavaScript language and client-side scripting environment, as well as quick-reference material on core and client-side objects, methods, and properties. The new edition has been revised to cover JavaScript 1.5, and is particularly useful for developers working with the standards-compliant web browsers, such as Internet Explorer 6, Netscape 7, and Mozilla. Ideal as an introduction for beginners and a quick reference for advanced developers, this pocket-sized book is easy to take anywhere and serves as the perfect companion volume to the bestsellingJavaScript: The Definitive Guide, 4th Edition.O'Reilly's Pocket References have become a favorite among developers everywhere. By providing a wealth of important details in a concise, well-organized format, these handy books deliver just what you need to complete the task at hand. When you've reached a sticking point and need to get to the answer quickly, the newJavaScript Pocket Referenceis the book you'll want close at hand.Amazon.com ReviewAt 4.5 by 7 inches in size and only 89 pages long, the aptly namedJavaScript Pocket Referencewill really almost fit in your pocket. Use this guide as a companion to turn to when you're in doubt about that function syntax or you're drawing a blank on the JavaScript object model.The book concisely packs together the syntax of the scripting language, including summaries of expression and statement style. The real meat of the tiny title is an alphabetical listing of JavaScript objects, along with their associated methods, properties, and events. One nice feature of this section is the attention to the varying support between Microsoft and Netscape browser versions. However, this listing is useful only if you know what object you want to work with. Missing from the reference is a solutions-based reference to let you refresh your memory about how to do a particular task, such as validate a form field or roll over a graphic when the user moves the mouse.One drawback is the book's illustration of the object model--done only in a small diagram. This is a bit of a shame since this is one of the key topics most developers need help with. If you're rather familiar with JavaScript, this pocket reference will be helpful. New coders, however, will likely find it insufficient.--Stephen W. PlainAbout the AuthorDavid Flanagan is a computer programmer who spends most of his time writing about JavaScript and Java.
