I noticed that on old computers (Windows 95, I think, and certainly 2000 and XP) where it would classify .js files as executables. I was about 11-14 so I didn't understand much of Windows at the time, let alone in a foreign language (I'm Dutch) when I wasn't even allowed to use the Internet (dialing up was expensive per-minute stuff), but yeah I remember that.

Still, I've never heard of anyone using Javascript or VBScript to automate anything. It's either powershell (these days), cmd scripts or custom .NET software. I've never even heard anyone mention using javascript in Windows (until apps came around in Windows 8) and vbs is only ever patchwork for legacy third-party software products as far as I've seen in my sysadmin days.
