Professional JavaScript for Web Developers

Professional JavaScript for Web Developers, 2nd Edition, provides a developer-level introduction along with the more advanced and useful features of JavaScript. Starting at the beginning, the book explores how JavaScript originated and evolved into what it is today. A detailed discussion of the components that make up a JavaScript implementation follows, with specific focus on standards such as ECMAScript and the Document Object Model (DOM). The differences in JavaScript implementations used in different popular web browsers are also discussed. Building on that base, the book moves on to cover basic concepts of JavaScript including its version of object-oriented programming, inheritance, and its use in various markup languages such as HTML. An in-depth examination of events and event handling is followed by an exploration of browser detection techniques and a guide to using regular expressions in JavaScript. The book then takes all this knowledge and applies it to creating dynamic user interfaces. The last part of the book is focused on advanced topics, including performance/memory optimization, best practices, and a look at where JavaScript is going in the future. This book is aimed at three groups of readers: Experienced developers familiar with object-oriented programming who are looking to learn JavaScript as it relates to traditional OO languages such as Java and C++ Web application developers attempting to enhance the usability of their web sites and web applications Novice JavaScript developers aiming to better understand the language In addition, familiarity with the following related technologies is a strong indicator that this book is for you: Java PHP ASP.NET HTML CSS XML This book is not aimed at beginners who lack a basic computer science background or those looking to add some simple user interactions to web sites. These readers should instead refer to Wrox's Beginning JavaScript, 3rd Edition (Wiley, 2007)
