Microsoft's had JScript and JScript.NET for server programming for a while and recently added Managed JScript: http://en.wikipedia.org/wiki/JScript http://en.wikipedia.org/wiki/JScript It's never really taken off, though Microsoft always pushed VBScript over JScript and C#/VB.NET over the managed JScripts. I used server-side JScript a little back in the old school ASP days and actually found it pretty confusing having both server and client code in the same language, though it sounded appealing in theory. More to wrap your head around. I do admit a second love with client-side JavaScript after the recent resurgence, but I definitely don't see it displacing Python, Ruby, or even Perl anytime soon. The core language is nice, but it's got a long ways to go.
