What Are Thunks?

• Thunks are functions that serve to delay execution of some code

• Useful for moving logic around to be executed asynchronously

Why is this useful for Redux?

• Sometimes dispatching an action needs to happen somewhere down the line rather than immediately as a reaction to an event

• Ajax requests to APIs don't update state in response to an event, they update state in a response to data returned by API call

Redux Thunk

• Provided as Redux middleware

• Allows for action creators to return not just an action, but a function that accepts dispatch

• Within the function, dispatch can then be called whenever the user likes
