# Asynchronous Actions ———————————- ## Thunking for Data:
- Thunkis middleware allows you to write action creators that return a function instead of an action. The thunk can be used to delay the dispatch of an action, or to dispatch only if a certain condition is met.
- Using Redux actions to connect to remote APIs via Thunk Middleware.
- Thunk will inspects every dispatched action and then either lets it go through (in the case of a normal action that returns an object) or it processes the function and then dispatches what that function returns.
- In Redux, middleware is implemented as a curried function that ultimately evaluates the action and determines whether it’s a function or not. If so, it gets invoked with the store’s dispatch() and getState() methods. Otherwise (a normal action creator), it simply runs your action.
- Thunk provides more stability and error checking for us.
