O(2^n) 😥

Love simplicity and ease of using || for returning the first 'truthy' value

this solution is recursive (see last lines)

Please, somebody, explain me, why code continue to execute after first condition that returns false. I thought keyword "return" stops the function

lucky you ;)

hello,
I don't understand why you solution is acceped if one of the RGB value is higher than 255?
Because 256 in hex is 3 characters (100), so your function will return more than 6 characters. Which should return an error.

Can you explain me?

How do you deal with ! or ?....
your function will return !ay and ?ay.
