Each middleware receives [`Store`](Store.md)'s [`dispatch`](Store.md#dispatchaction) and [`getState`](Store.md#getState) functions as named arguments, and returns a function. That function will be given the `next` middleware's dispatch method, and is expected to return a function of `action` calling `next(action)` with a potentially different argument, or at a different time, or maybe not calling it at all. The last middleware in the chain will receive the real store's [`dispatch`](Store.md#dispatchaction) method as the `next` parameter, thus ending the chain. So, the middleware signature is `({ getState, dispatch }) => next => action`.
