What does “recursion” mean?

recursion


Oh, this one is so cool — and a little mind-bending!

So "recursion" is when something refers back to itself, or repeats itself as part of its own process. It's a big word in computer programming, but you can see it in real life too.

Imagine you're standing between two mirrors facing each other — you see yourself reflected forever, inside itself, inside itself… that's recursion! In coding, a function can "call itself" to solve a problem, like saying "to do this task, first do this same task on a smaller version."

There's even a classic joke: if you search "recursion" online, Google says "Did you mean: recursion?" — because it loops back to itself, get it? 😄

Basically, recursion means something that keeps looping back into itself to work or explain itself.
