JavaScript
is a versatile language. It can be used to create
menus, validate forms, provide interactive calendars,
post the current day's headlines, produce background
effects on a Web page, track a visitor's history
on your site, and play games, among many other
things. That's probably why it's one of the
most popular languages on the World Wide Web.
Netscape created JavaScript in 1995. Originally
called "LiveScript," it was designed
to make Web pages more interactive. In the beginning
the language was plagued with security problems
which, for the most part, have been overcome.
The current version of JavaScript is 1.5. |
