// Create a Promise.
const promise2 = new Promise((resolve, reject) => {
// After 500 milliseconds rejects the second promise.

// Try executing the Promises.
(async function () {
try {
const data = await Promise.any([promise1, promise2]);
console.log(data);
} catch (error) {
// If all Promises gets rejected, then this try-catch block will handle
