function recursiveFunction(N) { let counter = 0; if (N > 0) { counter = counter + 1; recursiveFunction(N - 1); } // console.log(counter) } recursiveFunction(3); // 3 3 3 ? Explain what the output of the function will be and why. Also, identify any issues with the current implementation of the recursive function and suggest how to fix it to correctly count and log the number of recursive calls.

In the current implementation of the function:

function recursiveFunction(N) {
  let counter = 0;
  if (N > 0) {
    counter = counter + 1;
    recursiveFunction(N - 1);
  }
  // console.log(counter)
}
recursiveFunction(3);

The variable counter is re-initialized on each call, so it does not accumulate values between calls. As a result, even if you uncomment console.log(counter), it will print 1 or 0 at each recursion level, not the total number of calls.

Also, the function does not return or output the final value.

To correctly count the number of recursive calls, you can do the following:

function recursiveFunction(N) {
  if (N <= 0) return 0;
  return 1 + recursiveFunction(N - 1);
}

const count = recursiveFunction(3);
console.log(count); // 3

Here, the function returns the number of calls by adding 1 for the current call and the result of the recursive call. The total number of calls — 3 — is then outputted.
