Just tried out your code and it works.

It means your code returns undefined (does it actually return something?) whereas it is expected to return "raider".

cringe 😶

I added the 3 consecutive array elements into a list so i could use the count() function to find which one of them is only once in there :)

you're the one with both pieces of code and the knowledge of which test case failed. see if the js version produces the same answer, verify manually, etc

most likely though? you didn't try the same expression. they are different languages, so if you just copied the code, then js code doesn't do the same thing when executed by python

Why say things like this when people are trying to learn? Do you feel better about yourself?

Use spoiler flag next time please.

bad tests :P?

return false;
