    About Reactive Java 9

    Reactive programming is a programming paradigm that is different from what most developers are used to. It is really powerful and flexible. Understanding it properly and using it wisely can bring a lot of benefits to your applications.

    There is immense interest in Reactive programming right now. While most people can start with it quickly, it’s not always obvious what the differences are between some reactive concepts. RxJava 2.0 is the library we’ll use to put all these concepts into practice, and it will help us develop a robust and well-structured application.
