Normally I have a severe allergic reaction to anyone trying to do anything serious with Javascript, but this looks like a legitimately good idea and a decent innovation on how shells work.
I'm beginning to think that it isn't Javascript that I hate, it's the way people use it (i.e. to build bloated, slow, terrible webapps). But this is actually pretty cool. JS is shockingly decent at text processing so repurposing it as a shell language kinda makes sense.
It's a bit verbose for a shell language (all the async stuff tends to just get in the way in my experience using it like that), but it's great in the sense that everything can be treated as "text" and the functional bits work well when parsing over lines.
