With promises, we accomplish this by creating a promise chain. the api design of promises makes this great, because callbacks are attached to the returned promise object, instead of being passed into a function. here's the magic: the then () function returns a new promise, different from the original: js.

Promises are the foundation of asynchronous programming in modern javascript. a promise is an object returned by an asynchronous function, which represents the current state of the operation. Let promise = new promise(function(resolve, reject) { make an asynchronous call and either resolve or reject }); in most cases, a promise may be used for an asynchronous operation. however, technically, you can resolve reject on both synchronous and asynchronous operations. hang on, don't we have callback functions for async operations? oh, yes!.
