yeah, i think that's the problem but also tried that and it keeps timing out

If you modify your isPalindrome function not to use chained calls (.split().reverse().join()), it might not timeout.

Thx! Glad to hear it. You can upvote this puzzle if you like it.

I got caught up on the position moving to the right if the number of digits increases for ages! Good puzzle though - definitely one of the better 6 kata ones.

Keeps on timing out - not sure if the server or me, but solution works.

I'm also getting this error, did you get it resolved?
