RxJS has become almost a standard in the emerging reactive Front-End world. If you’re not using it right now, you probably played with a few operators. In this talk we’re going to rewrite RxJS from scratch and take a look behind the curtains at the core components and the ideas behind this library. You’ll learn how to build Observables, Subscriptions and Operator, then we’ll introduce Schedulers and how they’re used in RxJS. If you fancy Reactive Programming, live coding or simply learning something new then… this talk is for you!
