Practice chat web app with Golang and Websocket

1. WebSocket(): Make an instance of the websocket

const socket = new WebSocket('ws://localhost:8000')

2. WebSocket.send(): Send a message to the server

socket.send('Hello, server!')

3. WebSocket.onopen: This event is triggered when the WebSocket connection is successfully opened.

socket.onopen = (event) => {
  console.log('WebSocket connection opened!');
};

4. WebSocket.onmessage: This event is triggered when a message is received from the server.

socket.onmessage = (event) => {
  console.log('Received message from server: ', event.data);
};

5. WebSocket.onclose: Triggered when the WebSocket is closed.

socket.onclose = (event) => {
  console.log('WebSocket connection closed!');
};

6. WebSocket.onerror: This event is triggered when a WebSocket error occurs.

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