Haskell is much more "MIT approach" than "New Jersey approach". For a better example, consider how the quick & dirty hack that is Javascript is now far, for more commercially important than the entire FP language family combined (although, it's worth noting, somewhat inspired by FP).

As of importance, I boldly compare JS to Middle Ages' plague.

It is very important but not the way it helps.

Closures are too small an addition comparing to huge step back in semantics. Side effects in JS are irrepressible.
