    It’s a common case that a page in your application will require some initial data before it can show anything useful. In this lesson we learn that ‘epics’ in redux-observable are just functions that return Observables. Mostly we see epics that begin as a filter on the incoming stream of redux actions, but in some cases this is not suitable and you might need to just have something running immediately, regardless of user input.
