+// &#128204; JavaScript Advanced - WebSockets
+
+// Welcome to the WebSockets section of the JavaScript Advanced tutorial!
+// Here, you'll learn how to implement real-time communication using WebSockets.
+
+// Creating a WebSocket Connection
+const socket = new WebSocket("wss://example.com/socket");
+
+// Event Listeners for WebSocket
+// Connection opened
+socket.addEventListener("open", (event) => {
+  console.log("Connected to WebSocket server");
+  socket.send("Hello Server!"); // Sending data
+});
+
+// Receiving messages
+socket.addEventListener("message", (event) => {
+  console.log("Message from server:", event.data);
+});
+
+// Handling errors
+socket.addEventListener("error", (event) => {
+  console.error("WebSocket error:", event);
+});
+
+// Connection closed
+socket.addEventListener("close", (event) => {
+  console.log("WebSocket connection closed:", event);
+});
+
+// Sending JSON Data
+const jsonData = JSON.stringify({ user: "JohnDoe", message: "Hello!" });
+socket.send(jsonData);
+
+// &#128161; WebSockets are great for chat apps, live notifications, and real-time collaboration!
