Its appeal was that it was a subset of Visual Basic for Applications (VBA), the most widely used programming language in the world, and hence promised to make Internet programming easy not only for the huge installed base of VB/VBA programmers, but also for new programmers.

But for the most part, VBScript failed to deliver on its promise as a client-side scripting language. The problem wasn’t the language or its capabilities; rather, VBScript suffered because it was the second language to arrive in the arena of client-side scripting and was never able to supplant its rival, JavaScript.
