A function that returns itself and has a base case. for example, let the base case, f(0) be 1 Then, you want to have f(1)=1, f(2)=2, f(3)=6, f+4)=24, you return n*f(n-1) A function sample: def fun(x) if x==0 return 1 else return fun(x-1)*x end end

Recursion, basically, means applying a code on a big thing, finding a smaller version of the big thing in the thing itself, then applying the same script to each smaller thing in the big thing. My best example is folder operations: If you recurse, you do the same operation on each folder within the folder itself.
