This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.

Synopsis
error.messageDescription
The message property of an Error object (or of an
instance of any subclass of Error) is intended to contain a
human-readable string that provides details about the error or
exception that occurred. If a message argument is passed to the
Error( ) constructor, this message becomes the
value of the message property. If no message
argument is passed, an Error object inherits an
implementation-defined default value (which may be the empty string)
for this property.
