Many recursion problems can be solved with an iterative method, (i.e.or using a [[Loop Structures|loop]] of some sort (usually recursion and iteration are contrasted in programming, even though recursion is a specific type of iteration). In some languages, the factorial example is best done with a loop. If loop structures are not available (or not allowed), recursion is a good way to go. Many languages are designed to favor recursion over explicit looping, using ''tail-recursion optimization'' to convert recursive calls into loop structures. [[Scheme]] is a notable example.
