What is an Operator in Combine?
Combine declares publishers to expose values that can change over time, and subscribers to receive those values from the publishers. And the methods that operate on values coming from a publisher are called operators.
Each operator returns a publisher that, receives the values, manipulates them, and then sends them to its subscribers.
Operators are at the heart of every reactive Framework. It allows manipulating items as they go from observable to observer.
