Whats wrong with my attempt at JavaScript factorial?

Question

Ive attempted to make a factorial. The code below should return 24 (4x3x2x1) however it actually returns 12.

const fact = (no) => {
  let no2 = no;

  if (no > 1) {
    no--;
    no2 = no2 * no;
  }

  console.log(no2);
}

fact(4);

Answer 1

Doh! Id confused if with while

const fact = (no) => {
  let no2 = no;

  while (no > 1) {
    no--;
    no2 = no2 * no;
  }

  console.log(no2);
}

fact(4);
