Generally, we write scripts in either Microsoft JScript or VBScript, the two script engines that ship with Microsoft Windows 98, 2000 and Millennium Editions. We can use other script engines, such as Perl, REXX, and Python, with Windows Script Host.
A stand-alone script written in JScript has the .js extension; a stand-alone script written in VBScript has the .vbs extension. These extensions are registered with Windows. When we run one of these types of files, Windows starts Windows Script Host, which invokes the associated script engine to interpret and run the file.
