JavaScript Promises, Callbacks, and Async/Await for Beginners are great and solve the looping problem with callbacks. The core idea behind promises is that a promise represents the result of an asynchronous operation. A promise in JavaScript is the same promise that we make in our life.

And if the promise is never fulfilled by me then I failed to keep my promise.
