Microsoft's Visual Basic Scripting Edition is a scaled down version of Visual Basic. While it doesn't offer the functionality of Visual Basic, it does provide a powerful, easy to learn tool that can be used to add interaction to your web pages. If you are already experienced in either Visual Basic or Visual Basic for Applications, you will find working with VBScript easy and should be immediately productive. Don't be concerned if you haven't worked in another version of Visual Basic. VBScript is easy to learn, even for the novice developer.

How Does it Work?
When a VBScript is inserted into a HTML document, the Internet browser will read the HTML and interpret the VBScript. The VBScript can be executed immediately, or at a later event.
