It lets you to correlate handlers with the ultimate success value or failure reason of an asynchronous activity. As a result, asynchronous methods can return the same values as synchronous methods: Instead of giving the final value right away, the asynchronous method returns a promise to supply it at a later time.
Promise has a unique 'then' method that is used to give resolve and refuse callbacks. It worked the same as before, but now that we've included a resolve function, our promise will execute it when it's done and send it a message.
