A promise is an operation that is completed in the future and helps developers to implement asynchronous code. Promises are preferred over callback functions as promises are much cleaner hence improving readability and debugging of the code. It has better error handling as well as multiple asynchronous operations are better handled with promises. A promise can be fulfilled, rejected or it is pending. This post explains Promises in JavaScript and discusses Promises with the help of an example.
