Chapter 1: Introduction

What is VBScript?

VBScript is a client-side scripting language like JavaScript.

VB Script stands for Visual Basic Script and it is a light version of Microsoft Visual Basic.

The syntax of VBScript is very similar to that of Visual Basic.

VBScript was developed by Microsoft with the intention of developing dynamic web pages.

In other words, if you want your webpage to be more lively and interactive, then you can incorporate VBScript in your code.

VBScript is just a scripting language.

So, it cannot run its code on its own.

It needs a bigger programming language to host it.

Right now, there are 3 environments where VB Script can run.

IIS (Internet Information Server) – Microsoft’s web server

WSH (Windows Script Host)– The native hosting environment of the Windows OS

IE (Internet Explorer)– The simplest hosting environment we can use to run VBScripts

Disadvantage of VBScript

The main disadvantage of VBScript is that most browsers except Internet Explorer will not process VBScript code.

In other words, 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
