Script is the coding technology that you can use to make your traditional Web pages come to life. With script you can make use of (or leverage) all the latest browser technologies, such as CSS and DHTML, and create cutting edge, compelling Web pages!
Scripting is also used server-side - ASP scripts are just one example, of this.
Scripting can seem complicated or hard to learn but trust us when we say that it isn't. A few simple examples are all it takes to get the basics down. From that you can build on what you've learned and go on to create special, custom effects and applications.
