Although Visual Basuc Script is similar syntactically to visual basic (VB) and Visual Basic for Applications (VBA), it is quite a different animal. Like Visual Basic for Applications (VBA), Visual Basic Script (VBS) is also an embedded language and cannot be compiled into a stand-alone application or executable. However, Visual Basic Script (VBS) depends on a scripting host, which is a special application that knows how to compile and execute plain-text Visual Basic Script code at runtime. Originally, Microsoft created Visual Basic Script as an alternative to Netscape's JavaScript. Besides a simple desire to beat Netscape at their own game, Microsoft wanted to provide a way for Visual Basic developers to embed script code in plain-text HTML pages, which can't be done with design-time-compiled Visual Basic and Visual Basic for applications. Over time, Microsoft expanded support for Visual Basic Script beyond simple client-side HTML scripting in Microsoft's Internet Explorer web browser.
