Rule proposal: no-useless-recursion

👍

Disallow simple recursive function.

function foo(bar) {
  if (bar.baz) {
    return foo(bar.baz);
  }

  return bar;
}

function foo(bar) {
  while (bar.baz) {
    bar = bar.baz:
  }

  return bar;
}

function foo(bar) {
  for (; bar.baz; bar = bar.baz) {}

  return bar;
}

function foo(bar) {
  if (Array.isArray(bar)) {
    return bar.map(baz => foo(bar));
  }

  return bar;
}

I'm not sure how to define "simple".
