This execute 30 times faster. What am I doing wrong?
hash = ({0 : 'water freezes at 0°C', 100 : 'water boils at 100°C'})
fnb = (temp) => hash[temp] || 'nothing special happens at ' + temp + '°C'

I think Haskell for example just throws exception if you miss on pattern match and don't have default case. The types have to match anyway before hand but the values cannot be known before the computation.

Good to see you back! Also is that a new mic?

Anyway, have you thought about a Patreon?
