Impractical how? I'm curious. Writing JS strikes me as impractical from the get-go. Writing in a managed language that will compile down to JS and give you an escape hatch for when you really need it strikes me as far more practical in the long run.
To clarify, what I mean is that someone who can't learn Elm, PureScript, Bucklescript or the like, very likely isn't a very inquisitive person and isn't someone I'd like to work with. On top of that, someone who can't see why you'd want to write in any of those languages instead of JS very likely isn't someone who I would want to work with, for fairly obvious reasons.
