Operator
Explore how RxJava operators modify Observable emissions to simplify business logic in reactive programming. Understand the use of map and filter operators and the benefits of a fluent interface that supports method chaining for more readable and maintainable code.

Operators are very powerful constructs that allow us to declaratively modify item emissions of an Observable including the Observable/s themselves.
Through operator use, we can focus on the business logic that makes our applications interesting rather than concerning ourselves with low-level details of an imperative approach. Some of the most common operations found in functional programming, such as map, filter, reduce, and so on, can also be applied to an Observable stream.
