Reusing Operator Chains
Understand how to reuse operator chains in RxJava by leveraging ObservableTransformer and the compose operator. This lesson teaches how to encapsulate multiple operators for better code reuse and maintainability in reactive streams.

Declarative approach
As mentioned earlier in RxJava Core Components, 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.
Repeating operator chains
As such, we might find ourselves repeating the same chain of operators in parts of our codebase. For ...
