Promise objects represent events that will occur in the future and are used to deliver messages for asynchronous operations. With the Promise object, asynchronous operations can be expressed as a synchronous operation process, avoiding layers of nested callback functions. In addition, Promise objects provide a unified interface, making it easier to control asynchronous operations.
