Since 181 People completed the Kata using Javascript I'm pretty sure it has something to do with my code but I really have no idea.
I pass all the basic tests but when I try the random tests I get the following Error (on the first Random Test):

TypeError: a1[s].split is not a function

Great Kata! I really had fun solving it.
