One form can be converted to the other, with one notable restriction: many "popular" languages (C/Java/normal Python) do not support TCO/TCE (tail-call-optimization/tail-call-elimination) and thus using recursion will 'add extra data to the stack' each time a method calls itself recursively.

So in C and Java, iteration is idiomatic, whereas in Scheme or Haskell, recursion is idiomatic.
