In typical O"Reilly & Associates fashion, this book documents every nuance of the JavaScript 1.1 language specification. It may appear dry on the surface (many pages have the spare style of UNIX online documentation), but this is the book you"ll pull off your shelf when you want to know which method returns the primitive value of an object. Flanagan"s book comes out ahead of its competitors in a few other areas, too. JavaScript features a useful discussion of the limited JavaScript support found in Microsoft Internet Explorer and provides excellent documentation of LiveConnect, the software that allows JavaScript to communicate with Java applets. It also offers a taste of what"s in store for the just-released JavaScript 1.2. With a relatively small number of examples and no CD-ROM, this guide is more of a reference than a tutorial. It will serve experienced JavaScript programmers far better than those who are just starting out with the language.
