Thanks Johan! I have a lot of things to read about so I'll come back to this as soon as I have time xD

JS

random generator sometimes generates value 0 for discount.

PY

missing random tests

Example in description should be removed

"apple     apple dog cat" --> 1

There's no test case with more than 1 space (js and py), if there were a lot of regex solutions would be invalidated

We had the same thought but yours is much cleaner than mine :P

AAAH I still have a lot to learn

Sorry, forgot.

Maybe it's not an issue but wasn't there a prettier way to fail a test than yelling an error?

Anyway, nice kata.

(JS)

function wheatFromChaff(values) {
  return values;
}
