When starting to dabble with JavaScript, the biggest challenge for most developers is understanding how to deal with asynchronous development. During this talk, we will cover some of the different ways to handle async programming like callbacks, promises, reactive streams and events. As we cover those, we will also plunge into some of the mechanics of the Node.js engine, namely the event loop. Developers attending this talk will have a better understanding of asynchronous programming and will have a few new tools to their belt to tackle those issues as they come.
