WebJan 10, 2013 · Recursion has more expressive power than iterative looping constructs: I say this because a while loop is equivalent to a tail recursive function and recursive functions need not be tail recursive. Powerful constructs are usually a bad thing because they allow … WebThe main difference between these two is that in recursion, we use function calls to execute the statements repeatedly inside the function body, while in iteration, we use loops like “for” and “while” to do the same. Iteration is faster and more space-efficient than recursion. So why do we even need recursion?
