JavaScript is the scripting language of the Web. Its widespread use in web applications, and support in all modern browsers and in server-side and administration environments, make it an essential part of the programmer's toolkit.Complexity and confusion in JavaScript come not from the language, but from the number of different implementations, each with widely varying support for different APIs and standards. Written from extensive programming experience gained in developing components for a major website, this book helps you navigate those difficulties.The accompanying CD not only presents this entire book in PDF format, fully hyperlinked and viewable with Acrobat ReaderTM, but provides a cross-referenced, lexical reference that includes over 3500 entries, giving an even more comprehensive, browser-based companion to the book.
