## What it is
Redux Thunk is the official thunk middleware for Redux that lets you write action creator functions containing logic which can interact with the store's dispatch and getState methods. It is included by default in Redux Toolkit and can be added manually to a classic Redux store via applyMiddleware.

## Use cases
- dispatch async actions like API fetches from Redux
- access current state inside action creators
- inject a custom API service argument into thunks for testing
- conditionally dispatch multiple actions based on state
- write reusable logic functions that interact with the Redux store

## When to choose
- you use Redux and need to handle async logic or side effects in action creators
- you use Redux Toolkit, which bundles this middleware by default
- you want a tiny, battle-tested middleware with a simple function-based pattern

## When to avoid
- you use Redux Toolkit's createAsyncThunk or RTK Query for data fetching
- you use a state management library with built-in async support like Zustand or MobX
- you need more powerful effect handling such as sagas or observables
