Node.js 22: Native WebSocket Client
Node.js 22 continues the trend of adding built-in features that previously required external packages.

Native WebSocket

No more installing ws or socket.io for basic WebSocket operations:

javascript

const ws = new WebSocket('wss://example.com');
ws.onmessage = (event) => {


  console.log(event.data);
};

ws.send('Hello, Server!');

Faster startup

Better memory management

Node.js remains the backbone of server-side JavaScript.
