RxJava

Since its inception in 2012, RxJava has slowly gained in popularity for enabling reactive programming on Android. It is now deemed as the go-to and leading reactive library. Many companies have adopted the reactive way of programming, including Google, with its release of Android Architecture Components, which has many reactive elements in its design.

In this course, you will learn the fundamental principles of RxJava which will serve as a foundation for experienced Android developers who are new to the library and want to start integrating it into their apps.

Reactive Programming with RxJava

## Declarative approach
As mentioned earlier in [RxJava Core Components](https://www.educative.io/courses/reactive-programming-rxjava/operator), using an operator should be kept single-purposed. If multiple transformations need to be applied to an emission, each transformation should be encapsulated in its own operator. This approach is **declarative**, or in other words, it describes _what_ should be done, not _how_ it should be done. This aids in readability.
