While discussing what I've written here with a colleague, I've come across another neat implementation using unfoldr from this article which I've missed.
unfoldr
fibs = unfoldr (\(a,b) -> Just (a,(b,a+b))) (0,1) take 10 fibs
unfoldr is a method that builds an array list (towards the right) when given an initial seed (in this case, 0 and 1).
Just is a term used in Haskell's Maybe type, which draws parallel to how Optionals work in Java. Think of it as Optional.of()
Just
Maybe
Optionals
Optional.of()
