JavaScript was developed by
Brendan Eich of Netscape; Java was developed at Sun Microsystems. While the two
languages share some common syntax, they were developed independently of each
other and for different audiences. Java is a full-fledged programming language
tailored for network computing; it includes hundreds of its own objects,
including objects for creating user interfaces that appear in Java applets (in
Web browsers) or standalone Java applications. In contrast, JavaScript relies
on whatever environment it's operating in for the user interface, such as a Web
document's form elements.
JavaScript was initially called LiveScript at Netscape
while it was under development. A licensing deal between Netscape and Sun at
the last minute let Netscape plug the "Java" name into the name of
its scripting language. Programmers use entirely different tools for Java and
JavaScript. It is also not uncommon for a programmer of one language to be
ignorant of the other. The two languages don't rely on each other and are
intended for different purposes. In some ways, the "Java" name on
JavaScript has confused the world's understanding of the differences between
the two. On the other hand, JavaScript is much easier to learn than Java and
can offer a gentle introduction for newcomers who want to graduate to Java and
the kinds of applications you can develop with it.
