Chapter 3. JavaScript API Reference
The rest of this book contains a quick-reference for the core and
client-side JavaScript APIs. It documents the complete core
JavaScript API, covers the legacy (Level 0) DOM API, and presents a
simplified view of the W3C Level 2 DOM API. Portions of that API not
relevant to JavaScript programmers working with HTML documents have
been omitted. The upper-right corner of the title block for each
reference entry contains information that states whether a feature is
part of the core or client-side API, and further indicates which
version of JavaScript, which browsers, or which version of the DOM
introduced the feature.
Because JavaScript is a loosely-typed language, there is not an
official set of class names for the classes and objects of the
JavaScript API, and they sometimes appear under different names in
different references. (For brevity, this book actually uses a
slightly different set of names than its big brother,
JavaScript: The Definitive Guide.) The following
table summarizes the reference entries that follow, and allows you to
quickly scan for the class or object you are interested in.
