Microsoft Visual Basic Scripting Edition, commonly known as VBScript, is a relative of the Visual Basic family, which includes the Microsoft Visual Basic Development System (the retail version of Visual Basic in its Enterprise, Professional, and Learning Editions) and Visual Basic for Applications (the language component of Visual Basic, which is included in the individual applications within Microsoft Office and Microsoft Project, as well as in a host of third-party applications).
VBScript is, for the most part, a subset of the Visual Basic for Applications programming language. It was developed so that the millions of Visual Basic developers could leverage their knowledge of VB/VBA in Internet scripting. One of the strengths of VBScript is that it uses the same familiar and easy syntax that has made VBA so popular as a programming language, making it very easy to learn for those who have some Visual Basic background. In addition, VBScript is fairly easy to learn for those without any programming experience.
