How does ws.OPEN work?

ws.OPEN is a predefined constant in the WebSocket API that represents the readyState value of an open connection, which means the WebSocket connection is established and ready for communication.

const WebSocket = require("ws");
const ws = new WebSocket("ws://localhost:8080");

ws.on("open", function () {
  console.log("WebSocket connection established");

  if (ws.readyState === ws.OPEN) {
    ws.send("Hello WebSocket!");
  }
});

ws.on("message", function (data) {
  console.log("Received message:", data);
});

In this example, the ws.readyState property is checked against ws.OPEN to ensure that the WebSocket connection is open before sending a message. If the connection is not open yet, the message will not be sent.
