JavaScript: Creating a Down Counter
Example: A counter that will count down from 20 in one second intervals
var counter = 20 // say we have a 20 seconds down counter var interval = setInterval(() => { if (counter-- < 0) { clearInterval(interval); } else { if (counter >= 0) { // we get here every second while counting } else { // timer has finished } } }, 1000); // 1000 is 1000mS or One Second
