Reactive programming sounds scary and complicated, but in reality it’s just a very natural way of working with asynchronous data streams in your code. Observables are a representation of these streams that allow us to listen and react when new values are emitted. 
 In the first part of the workshop we’ll take a deep dive in the world of Observables, explore the principles under which they operate, create our own, check out some common use-cases and see how they match up to Promises (the native way of handling async code in JavaScript). We’ll also have a look at the extensive and very powerful RxJS library that simplifies and enhances observables offering ways to create, transform combine and filter them. And we’ll wrap up with testing observables techniques, using ascii marble diagrams.
 RxJS and observables are also the backbone for the Angular framework and so for the second part of the workshop we’ll have a look at how Angular leverages the power of observables in it’s mechanisms to communicate data between components, routing, forms and http. Then we’ll look at some advanced patterns to manage complex async scenarios within an Angular application such as Observable Data Services, instant search, caching and others. For this second part of the workshop, some basic understanding of the main Angular concepts (modules, basics of creating and using components, communication, services, basic routing, basic http etc.) is needed in order to follow along with the examples.
 At the end of this session you will gain more confidence in programming with observables and leveraging their power in order to create truly reactive Angular (and not only) applications.
