Can you explain what middleware is in Redux?

Middleware in Redux is a way to extend Redux's capabilities. It allows you to intercept actions before they reach the reducer, enabling features like logging, crash reporting, or asynchronous actions.

How do I implement a custom middleware?

To implement custom middleware, you create a function that takes the store's dispatch and getState methods, and returns another function that takes the next middleware in the chain. This function will handle the action.

What are selectors and how do they work?

Selectors are functions that extract specific pieces of data from the Redux store state. They help in optimizing performance by memoizing the results.
