What are some pros/cons to using iterables (sagas) and observables in Redux?

Iterables (Sagas)

Pros

  • Most popular solution, so probably better community support.
  • Testing: very easy to mock side effects using "call" effect.

Cons

  • Lack of operators (retry, take, etc.).

Observables

Pros

  • Good tooling for visualising control flow, e.g. http://rxfiddle.net/.
  • Transferable skills to other languages (Rx).
  • Transferable skills to other domains (all async stuff, not just Redux).
  • Large collection of battle tested operators (retry, take, etc.).

Cons

  • Testing: harder to mock side effects.
