How do I implement a WebSocket client in JavaScript?

To implement a WebSocket client in JavaScript, you can use the WebSocket API. Here's a basic example:

const socket = new WebSocket('ws://yourserver.com/socket');

socket.onopen = function(event) {
    console.log('Connection established!');
};

socket.onmessage = function(event) {
    console.log('Message from server: ', event.data);
};

socket.onclose = function(event) {
    console.log('Connection closed: ', event);
};

socket.onerror = function(error) {
    console.error('WebSocket error: ', error);
};

What events can I listen to on the WebSocket client?

You can listen to several events on the WebSocket client:

• onopen: Triggered when the connection is established.
• onmessage: Triggered when a message is received from the server.
• onclose: Triggered when the connection is closed.
• onerror: Triggered when an error occurs.

Can I send messages to the server using this client?

Yes, you can send messages to the server using the send method. For example:

socket.send('Hello Server!');
