It's expected your answer to equal expected answer, so the expected value in the error message is 1 not -1. -1 is the value your function returned. Not a kata issue.

[[1,1,1],[0,2,2],[0,0,0]]: expected -1 to equal 1.

The test expects -1, although the correct answer is 1.

Yes, you're right, I don't know why I did it)

hey friend you already passed the key up in the EggList copmponent there is no need to pass it again down in the EasterEgg

Yes, I agree with you. And your solution is very accurate

If this solution is correct it means tests are weak.

Amazing Kata!

WTF?? ))

IIFE & NFE & recursion

Ok, but why? )

Really good solution!

I see this is the right test:

tailAndHead([1,2,3,4,5]) should return 945

Perhaps you forgot to correct the description? )

According to the description "The key has to be shortest of all possible keys that can be used to code the message: i.e. when the possible keys are 12 , 1212, 121212, your solution should return 12.". 19391 and 1939 may be used as a key. 1939 is shorter. I hope it helps.

I completed the first two katas.

But this does not change my question.
