What is Redux middleware and how does it work?

Redux middleware is a way to extend Redux's capabilities. It allows you to intercept actions before they reach the reducer, enabling you to perform side effects, logging, or even modifying actions.

Can you give me an example of a common middleware?

Sure! A common example is 'redux-thunk', which allows you to write action creators that return a function instead of an action. This is useful for handling asynchronous operations.

How do I set up middleware in my Redux store?

You can set up middleware by using the applyMiddleware function from Redux when creating your store. For example: createStore(reducer, applyMiddleware(thunk)).

Are there any other popular middleware I should know about?

Yes, other popular middleware include 'redux-saga' for handling side effects and 'redux-logger' for logging actions and state changes.
