VBScript - Visual Basic Scripting Edition is a late-bound and lightweight version of Microsoft's Visual Basic. It's used for both client-side scripting, typically with a browser (although Microsoft Internet Explorer only supports it), and more commonly as the server-side language of choice with ASP.
VBScript, the newest member of the Visual Basic family of programming languages, brings active scripting to a wide variety of environments, including Web client scripting in Microsoft Internet Explorer version 3.0 and Web server scripting in Microsoft Internet Information Server version 3.0.
