Could someone please explain to me where/how this passes the last test where you have to only replace the last occurrence of the number? When I tried the replace method, foo99bar99 or whatever became foo100bar99 or foo100bar100. I can't figure out what part of this is addressing that.

Oh clever! I never thought of the idea that if it's not 9 at the end we only needed to update the final digit.

It doesn't, it turns 9s into 10s and replaces the match with the new number

clever

tysm!

this sign converts string value to number, example '1' (string) will be 1 (number)

same :c

can someone explain how does a ' + e + 1' section work? i mean why theres a '+' after a question mark?
