It's as if you're looking for reasons to shit on OP. Come on.

For most websites; there's no reason for JS. For something like this? That's just being a prick about JS for being a prick about JS's sake.

I was also rather disappointed that when curling this "shell", nothing happens. Or rather, you just get the minified javascript just like it would give to your browser and using a shell to access this would-be-shell does absolutely nothing. And no tab complete, up arrow, and I see elsewhere in the thread that even ./ didn't use to work. It seems the author has very limited experience with shells and made an -- I would say 'elaborate' but it wasn't -- rick rolling page.
