// Create a Promise.
const promise1 = new Promise((resolve, reject) => {
// After 2 seconds resolve the first promise.
setTimeout(() => resolve("The first promise has been resolved."), 2000);
});
// Create a Promise.
const promise2 = new Promise((resolve, reject) => {
// After 1 second resolve the second promise.
setTimeout(() => resolve("The second promise has been resolved."), 1000);
});
// Create a Promise.
const promise3 = new Promise((resolve, reject) => {
// After 3 seconds resolve the third promise.
setTimeout(() => resolve("The third promise has been resolved."), 3000);
});
(async function () {
const data = await Promise.any([promise1, promise2, promise3]);
// Print the data returned from the first resolved Promise.
console.log(data);
// The above will print: The second promise has been resolved.
})();
