The dispatched action updateDone mutates state before post and profile data are in the store. This makes async/await unpredictable since we don't know when a dispatch with response data executes. We can wait for a response via await inside the thunk itself but lose all control outside of the function.

What does Dispatch return in Redux?

Redux Thunk is a middleware that lets you call action creators that return a function instead of an action object.

when an action is dispatched, or when we invoke dispatch and pass in an action object, the dispatch function calls our reducer and passes in the current state and the action object! ... So when the dispatch function does this - reducer(currentState, action); - that function call is going to return a brand new state object.

Can I dispatch an action in reducer?

When your reducer has finished and returned the new application state, asyncDispatch will trigger store. dispatch with whatever action you give to it. You might try using a library like redux-saga. It allows for a very clean way to sequence async functions, fire off actions, use delays and more.
