2017 AIM HDC

If you are a JavaScript developer, you’ve most likely encountered “callback hell”: The scenario where you are buried deep into a pyramid of nested callback functions and have no idea how to get yourself out. You may have graduated to Promises which can alleviate some of the stress, however, they too can get a little messy once you start chaining .then() after .then() after .then(). Luckily JavaScript has added a new API for Asynchronous Functions. In this session we’ll explore how to use Asynchronous Functions. We’ll see how they can make complex code like AJAX requests cleaner and easier to read. We’ll also look at some async error handling techniques.
