Simple JavaScript clock

Although this code can easily be found on the Internet, we still write a simple JavaScript clock

Clock:

<div id="clock"></div>

<script>

function clock(){

    let date = new Date(),
        hours = date.getHours(),
        minutes = date.getMinutes(),
        seconds = date.getSeconds();

    if (hours < 10) hours = '0' + hours;
    if (minutes < 10) minutes = '0' + minutes;
    if (seconds < 10) seconds = '0' + seconds;

    let time = hours + ':' + minutes + ':' + seconds;

    document.getElementById('clock').innerText = time;

    setTimeout(() =>{
        clock();
    }, 1000);
}

clock();

</script>
