java script timer code example

Example 1: javascript set delay

var delayInMilliseconds = 1000; //1 second

setTimeout(function() {
  //your code to be executed after 1 second
}, delayInMilliseconds);

Example 2: timer in javascript

//single event i.e. alarm, time in milliseconds
var timeout = setTimeout(function(){yourFunction()},10000);
//repeated events, gap in milliseconds
var interval = setInterval(function(){yourFunction()},1000);

Example 3: javascipt delay

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

console.log("Hello");
sleep(2000).then(() => { console.log("World!"); });

Example 4: How to make a timer in javascript

const milliseconds = Date.now() - start;

console.log('Seconds passed = ' + millis / 1000);
// Seconds passed = *Time passed*

Example 5: javascipt delay

async function delay(delayInms) {
      return new Promise(resolve  => {
        setTimeout(() => {
          resolve(2);
        }, delayInms);
      });
    }
    async function sample() {
      console.log('a');
      console.log('waiting...')
      let delayres = await delay(3000);
      console.log('b');
    }
    sample();

Example 6: onclick timer javascript

document.getElementById("gameStart").addEventListener("click", function(){
    var timeleft = 15;

    var downloadTimer = setInterval(function function1(){
    document.getElementById("countdown").innerHTML = timeleft + 
    " "+"seconds remaining";

    timeleft -= 1;
    if(timeleft <= 0){
        clearInterval(downloadTimer);
        document.getElementById("countdown").innerHTML = "Time is up!"
