Как запустить код только когда доскроллил до него (js без библиотек)

function playNumber(one, two, three, four, five, six, seven, eight, nine, ten, selector ) {
        
        const number = document.querySelector(selector);
        let current = 0;
            setInterval(() => {
                if(current <= six) {
                    number.innerHTML = current++;
                }
            }, one);
            setInterval(() => {
                if(current <= seven) {
                    number.innerHTML = current++;
                }
            }, two);
            setInterval(() => {
                if(current <= eight) {
                    number.innerHTML = current++;
                }
            }, three);
            setInterval(() => {
                if(current <= nine) {
                    number.innerHTML = current++;
                }
            }, four);
            setInterval(() => {
                if(current <= ten) {
                    number.innerHTML = current++;
                }
            }, five);  
    }
        
let isPlayed = false;
document.getElementById('test').addEventListener('scroll', (e) => {
  const {scrollHeight, clientHeight, scrollTop} = e.target;
  if (!isPlayed && scrollHeight - (clientHeight + scrollTop) < 100) {
    playNumber(5, 40,200,500,2000,120,140,147,149,150, '.numberOne');
    playNumber(0, 20,100,300,2000,900,980,990,999,1000, '.numberTwo');
    isPlayed = true;
  }
});
