Why doesn't recursive function work with setInterval?

Question

JavaScript

When pressed, the function does not fire
Or can a recursive function be combined with setInterval ? It works without setInterval .

let button = document.querySelector('.button');

let pow = (n) => {
    if(n == 1) {
      return n;
    }
    else {
      return n * pow(n - 1)
    }
}

button.onclick = () => {
  console.log(setInterval(pow, 1000, 5));
}

Answer 1

why doesn't it work, everything works
