Answer 1

socket.use() is basically where you can add middleware functions, which just means that the function passed as the parameter for thesocket.use() function is executed for every piece of info received.

Here's the socket.io docs

Answer 2

socketio.use() method is same like as express_app.use() method , means both are used for passing middleware-functions , where middleware-functions can control/manipulate every upcoming requests/response on the server.
