Might also be an inappropriate application of recursion in a language where loops are more common. I've seen people who learn new stuff go overboard with clever code in production that is less readable for their peers.

Recursion shouldn't even be considered advanced though, just like classes and first class functions. I'm all for making code as boring as possible, but to me understanding at least these concepts is a requirement of entering the profession of software development.

Sometimes recursion is the good solution, For example a back-tracking solution is more simple with recursion than without it.
