what does it do? too much syntax. Lisp is all I can take for my puny brain.

It's functional programming. Lisp weenies aren't expected to understand it.

I was asking honestly. It's too much syntax. I have reached Lisp satori and do not need ``Haskell''

J can:
+/%#
+/ is sum (reduce by addition).
% is division.
# is length.
Thus this phrase computes the sum divided by the length.
