Hi. My name is Andre. In this series of lessons, we will learn about ReactiveX, a library for Reactive programming. I'm talking about RxJS. This series will be a deep dive into what the observable type is and the different ways of creating observables.
For the purpose of this series, we're going to study Version 5. Because it's newer, it's more likely to last over time. It's also being used in Angular too. Apart from minor differences, it doesn't matter which version we use, either v4 or v5. The overall concept is the same. We're going to look at the observable type in details. Later on, we're going to see about creation functions.
