HTML5 WebSockets

 HTML5 WebSockets

WebSockets enable bidirectional communication between a client and a server over a single, long-lived connection. It allows real-time data exchange. Here's an example:

<script>

  const socket = new WebSocket("ws://example.com/socket");

  socket.onopen = function() {

    console.log("WebSocket connection established.");

    socket.send("Hello, server!");

  };

  socket.onmessage = function(event) {

    console.log("Received message from server:", event.data);

  };

  socket.onclose = function() {

    console.log("WebSocket connection closed.");

  };

</script>
