A Deep-Dive into ES6 Promises

About this presentation

Promises are an awesome way to manage asynchronous code in both client and server-side Javascript. And now that native promises have landed in ES6, it’s a great time to get started if you haven’t used them before. That said, once you get beyond the basic concepts, it not always obvious what their full potential is. In this talk we’ll dive deep into using ES6 promises. We’ll see how promise chaining and composition makes it easy to manage complex sequences of asynchronous operations. We’ll learn how to correctly handle exceptions with promises. Finally, we’ll talk about strategies for unit testing code that uses promises. You’ll leave this presentation understanding how you can fully leverage ES6 promises to write asynchronous code that is easier to comprehend and reason about. Promises are here to stay, and once you’ve seen the light, you won’t want to go back.
