JavaScript
From The Glossary of Digital Photography
A simple programming language designed to run on web pages. Although both Java and JavaScript are owned by Sun Microsystems, JavaScript is only distantly related to the Java programming language. Netscape developed JavaScript. JavaScript is known as a scripting language, that is, a programming language in which each step is interpreted sequentially rather than being compiled and converted to machine language before beginning. The most common usage seen is on web pages to implement the mouse-over feature, where images change as the cursor is hovered over them.
