Congratulations! You are now prepared to dive into the RxJava world.
In this chapter, we covered the most essentials parts of RxJava. Later in this book, we will keep introducing more advanced concepts and techniques, but they will all rely on Observables (Flowables), Disposables, and Schedulers.
Maybe not all this stuff makes sense yet (the big picture) but with more examples and use cases that will follow, their differences will become much more clear and distinct.
