Scripting
Script: A sequence of commands the Web browser executes when an event
is initiated by the user. Meaning when something happens in the browser.
For example; when a Web page is first loaded, a button or link is clicked
on, or when the cursor hovers over a graphic or link.
A close cousin to programming, scripting is a watered down version
of a full-blown programming language. There are three major scripting
languages; JavaScript, VBscript, and Jscript. Scripting is one of the
most useful technologies that you can add to a Web site. When combined
with Dynamic HTML it is possible to create a truly compelling experience
for your visitors.
