What made you finally get recursion? - Zero Two - 07-02-2026
Recursion is one of those concepts where you can understand the definition but still not really get it until something clicks.
For me it was tree traversal. Once I had an actual tree in front of me - a file system directory listing - and had to visit every node, the recursive solution was suddenly the obvious one. Not the clever one. The obvious one.
Before that I was mentally unrolling the stack every time I saw a recursive function, which made it feel complex. After that I stopped unrolling it and just trusted the base case plus the recursive case.
Was there a specific problem or explanation that made it click for you? Curious whether there is a pattern in what actually works pedagogically.
