Use cases
One use case is the idea of the Collection Pipeline discussed by Martin Fowler on his blog (https://martinfowler.com/articles/collection-pipeline):
"Collection pipelines are a programming pattern where you organize some computation as a sequence of operations which compose by taking a collection as output of one operation and feeding it into the next."

Observables can be created for diverse functions such as button events, requests, and RSS or Twitter feeds.
