Asynchronous node.js websockets?

Question

Node.js

How to make a server on node.js asynchronous web sockets?
Or are they asynchronous out of the box? I myself came from Python and there I need to work with coroutines and async await.

Here I have no idea how to do it. Roughly speaking, you need a web socket server that can serve many connections at the same time.

There is this code:

wss.on('connection', function connection(ws) {
  ws.on('message', function incoming(message) {
    ws.send(message);
  });

});

Answer 1

all JS out of the box is asynchronous
