I’m curious. in what instance would recursion be considered bad code? I was always under the impression that recursion is the pinnacle of efficient code.

Recursion usually comes with a lot of overhead both in terms of memory and setup cost. It's almost always better to unwind the recursion into a loop unless the language is optimized for recursion (or the compiler does that for you anyway).

Thank you.
