Promises, Promises: An Exploration of Promises in Javascript

Topic

Promises are the most popular pattern for writing asynchronous JavaScript code, existing in some form in every client-side framework in widespread use today. We’ll give a conceptual intro to promises in general, and talk about ways they can make your code nicer. We’ll also spend some time on the past and future of promises in JavaScript: how we got to where we are, and what efforts are underway to standardize them in the browser and in the language. Finally, we’ll look at some bleeding-edge things you can do with promises, including combining them with the upcoming generators language feature for much simpler async code, and using them as proxies for remote objects (“promise pipelining”).
