execution order of middleware

[NeoLaner]

I have a question regarding the execution order of middleware and event handlers in Socket.IO.

Here's my current setup:

const io = require('socket.io')(server);

io.on('connection', (socket) => {
  console.log('A user connected');

  // Middleware to process events
  socket.use(([event, ...args], next) => {
    console.log(`Middleware: Event received - ${event}`);
    // Perform logging, authorization, rate limiting, etc.

    next(); // Pass control to the next middleware or event handler

    // Code here runs immediately after `next()`?
    console.log(`Middleware: Post-processing after event - ${event}`);
  });

  // Event listeners

  socket.on('example', (data) => {
    console.log('Example event handler executed', data);
    // Handle the 'example' event
  });

  socket.on('disconnect', () => {
    console.log('User disconnected');
  });
});

i want to know the codes after next function call in socket.use() runs immediately or wait all middlewares and event handler executed and then start to executing?
