Any code which walks a tree is almost certainly going to be using
recursion. This is everything from a chess game analyser, to image
processing software, to your browser when it's rendering a web page and
much more in-between.

There's a very good reason why every single course in coding or any form
of computer science is going to explain it to you at some stage in the
course. It's used a lot, in a lot of places.
