Reversed

What happens if you reverse the statements in printList?

Well, now the function is being called before printing the value of i. So the values are printed during the "unwind recursion" phase, after the base case is invoked. This would print the values in reverse (in other words, 5, 4, 3, 2, 1).

xxxxxxxxxx

function printList(i) {

  // base case

  if (i > 5) {

    return; // do nothing

  }

  // recursive case

  printList(i + 1);

  console.log(i);

}

printList(1);
