问为什么Why循环中的setInterval变成无限循环(JS)？

quester2()
function quester2() {
  for (i = 0; i <= finalCount; i++) {
    let K = Math.ceil(Math.random() * 2);
    if (K == 1) {
      setInterval(function () { console.log("one"); }, 1000);
      finalCount += 1;
      allIterations += 1;
      setInterval(function () { console.log("one or two?"); }, 1000);
    } else {
      setInterval(function () { console.log("one or two?"); }, 1000);
      allIterations += 1;
    }
  }
  console.log(finalCount);
  console.log(i);
}
