What is the role of middleware in Slim Framework?

Answer: Middleware in the Slim Framework acts as a filter for incoming HTTP requests and outgoing responses. It allows developers to add functionality such as authentication, logging, or CORS handling by processing requests before they reach the application logic and modifying responses before they are sent to the client. Middleware runs in a stack, enabling multiple layers of processing to be applied in a defined order.
