Being Asynchronous

Tuesday, October 10th, 2017, 5:30 PM

Dot catch! Dot catch!
- David Wood

Many of us know about the benefits of offloading concurrent I/O operations through the use of callbacks, libraries such as async and bluebird, or using the new Promise support in browsers and Node.js. But, do you know how these work, and when you should use them?

In this talk we will review the benefits, pitfalls, and ways to implement concurrent JavaScript code in Node.js and the browser. We'll look at the support for async/await, how this differs from callbacks and asynchronous libraries, and take a brief look at how these have been implemented to gain a better understanding of what's going on under the hood.

At the end of this talk you will be able to make more informed decisions about the use of synchronous API methods such as readFileSync, choosing to listen to error events, and why wrapping function calls in try..catch may or may not be useful.
