Please, NASM Translation
The kata isn't broken, your code is wrong, check how you use switch.

Not a kata issue then.
I think when you run this check:
(n.substring(0,1) === "4" && n.length === 13 || n.length === 16)
It should really be:
(n.substring(0,1) === "4" && (n.length === 13 || n.length === 16))
What failures are you getting? I cannot see your solution so I've no way to know what it is happening unfortunately.
