Javascript, thanks for the heads up.

When submitting my attempt, I am tested on the same string for s1 and s2, "jjvvvrrqqqqhhhhlxxxxhhggggguuzurrvvvtt". Somehow, it tells me that the expected output for all the uniqure characters in this string (s1 and s2 BOTH equal this string) is "ghjklpqrtuvwxyz". There is absolutely no k in this string, or a p, or w, etc.

I am also hit with 13 other errors of the same nature - how is this possible? Is there anyway this can be checked, because I know my solution is right, I pass 95%, but with these answers, it is obvious that the expected result is incorrect.

I also have screenshots saved locally
