what is vb script?

VBScript (short form of Visual Basic Script Edition) is an Active Scripting language interpreted via Microsoft's Windows Script Host. The language's syntax is a variation of Microsoft's Visual Basic programming language.
When employed in Internet Explorer, VBScript is very similar in function to JavaScript –- it processes code embedded in HTML. VBScript can be also used to create stand-alone HTML applications (file extension .hta) which require Internet Explorer 5 or later to run.
Web developers may prefer to use JavaScript instead for better compatibility with web browsers other than Internet Explorer.
