This is a screenshot of the jsfs -hosted editor “jedi”, editing its own source code:
Jedi is the first application developed specifically to run on jsfs. By beginning with an editor, it’s possible to bootstrap the developent of any other application and develop them from within jsfs itself. There is a lot more to do, obviously, but this is a significant development, and a major step toward making jsfs behave like a true general-purpose computing platform.
Jedi source code is available on Github now, future versions will be available directly via jsfs.
