A code example illustrating the difference between the paradigms of async/await and Reactive (Rx) extension?

Question

Both the System.Reactive extension for .NET and new C# 5.0 (.NET 4.5) async/await pursue (or based on) future and promises constructs paradigm (approach).

Can you gi

Answer 1

I like the table in the Reactive documentation: http://reactivex.io/intro.html

I have my own take on it where i add a third dimension non-composable/composable.

Non-composable:

       |  Single Item   | Multiple items
 ------|----------------|----------------
 Sync  | Function       | Iterable
 Async | Async function | Observable

Composable:

       |      Single Item      |       Multiple items
 ------|-----------------------|----------------------------
 Sync  | Higher order function | Linq/Ramda/java.util.stream
 Async | Future/promise        | Rx observable

And mind you that depending on the implementation, you can have futures and rx observables that can act both synchronously or asynchronously depending on whether what you are trying to do with them is synchronous or asynchrounous
