This reference is organized around the functionality of the JavaScript language. Sometimes you already know the name of an object or method, but don't know precisely where to look for it. This chapter contains tables of links to aid in this situation.

This book is a reference manual for the JavaScript language, including objects in the core language and both client-side and server-side extensions. JavaScript is Netscape's cross-platform, object-based scripting language for client and server applications.
