A scripting language developed by Netscape to enable Webauthors to design interactive sites. Although it shares many of the features and structures of the full Java language, it was developed independently. Javascript can interact with HTML source code, enabling Web authors to spice up their sites with dynamic content. JavaScript is endorsed by a number of software companies and is an open language that anyone can use without purchasing alicense. It is supported by recent browsers from Netscape andMicrosoft, though Internet Explorer supports only a subset, which Microsoft calls Jscript.
