 Definitions for javascript: The Free On-line Dictionary of Computing (27 SEP 03)
:
JavaScript
(Formerly "LiveScript") Netscape's simple,
cross-platform, {World-Wide Web} scripting language, only
very vaguely related to Java (which is a Sun trademark).
JavaScript is intimately tied to the {World-Wide Web}, and
currently runs in only three environments - as a server-side
scripting language, as an embedded language in
{server-parsed HTML}, and as an embedded language run in web
browsers where it is the most important part of DHTML.
JavaScript has a simplified C-like syntax and is tightly
integrated with the browser Document Object Model. It is
useful for implementing enhanced forms, simple web
database {front-ends}, and navigation enhancements.
JavaScript originated from Netscape and, for a time, only
their products supported it. Microsoft now supports a
work-alike called JScript. The resulting inconsistencies make
it difficult to write JavaScript that behaves the same in all
browsers. This could be attributed to the slow progress of
JavaScript through the standards bodies.
JavaScript runs "100x" slower than C, as it is purely
interpreted (Java runs "10x" slower than C code).
Netscape and allies say JavaScript is an "open standard" in
an effort to keep Microsoft from monopolising web software
as they have desktop software. Netscape and Sun have
co-operated to enable Java and JavaScript to exchange
messages and data.
