Below is a screencast of an introduction to RxJS Observables and how they integrate into Angular. First we will cover what Observables are and how RxJS helps us. Next we will learn how to use Observable Operators and create a Counter UI widget without Angular. Afterwards we will create a small Angular app to search the YouTube API using Observables.
