Is it correct to make loops recursive?

Question

JavaScript

JS example:

function test(){
  rnd = Math.floor(Math.random() * 10);
  //console.log(rnd);
  if (rnd==6)
    return rnd;
  else
    return test();
}

console.log(test());

Is it allowed to do so? If not, I'd like to understand why.

Answer 1

an example of heresy.
because all this is replaced by

function test(){
   return 6;
}

But in general, who forbids you, consider just an extra function call - an extra resource overhead.
but if you have only a few iterations there, then of course no one will notice it.

Answer 2

In JS, this is incorrect, since trailing (tail) recursion is not supported.
