let myPromise = new Promise(function(myResolve, myReject) {
  // "Producing Code" (May take some time)
  myResolve(); // when successful
  myReject();  // when error
});

async function myFunction() {
  return "Hello";
}

async function display() {
  let myPromise = new Promise(function(resolve) {
    setTimeout(function() {resolve("I love You !!");}, 3000);
