The main disadvantage of VB Script is that most browsers except Internet Explorer will not process VB Script code.
Means,if your site has visitors who use a web browser other than Internet Explorer like Chrome, Firefox or Opera, then VBScript will not be useful.
Moreover, VBScript will not run on computers that run on operating systems other than Microsoft Windows including Linux, Mac etc.
Like any other scripting language, VBScript has gone through many changes over the years.
