express middleware status code always 200

The Express middleware status code always returns 200 for each step. The following are the explanations for each step:

1. Request: The client makes a request to the server.
2. Middleware Execution: The Express middleware is executed to process the request.
3. Default Status Code: If the middleware does not explicitly set the status code, Express defaults to a status code of 200.
4. Response: The server sends a response back to the client with the status code set to 200.

These steps illustrate how the Express middleware handles status codes, ensuring that a 200 status code is returned if not explicitly defined.
