Linux command line emulator that can run scripts, in Javascript?

Hey I was just wondering if anyone has made a version of Debian written in Javascript, just for a test. I know it would not be able to do unlimited stuff, but what Javascript lets it have should be enough.

Here is a C64 emulato开发者_运维技巧r I have found, but it's too simple? http://www.kingsquare.nl/jsc64

Take a look at http://jpc.sourceforge.net/demos_linuxdemos.html

This sounds like a truly horrible idea to me. So it should be fun, good luck with it! :)
