Specific Differences.
Debbuging: VBScript doesn't have a debugger like VB.
Event Handlers: You don't have an editor in which you select an object and event to edit an event procedure.
Forms: VBScript doesn't have a form editor. You can't display forms. You put forms and controls on the Web page.
Compile: You don't compile a VBScript program into a EXE. file like you do in a VB program.
Distribution: You distribute your script as plain as old text, embedded in as HTML file.
Everyone can read your script.
