What is the simplest and highest abstraction client for websocket in javascript? I'll be writing a client for a finished game backend, that will be reverse engineered
There are several libraries available to help you work with WebSockets in JavaScript, each with varying levels of abstraction. If you're looking for the simplest and highest level of abstraction, you might want to consider using Socket.IO.

Socket.IO is a popular library that simplifies real-time, bidirectional communication between clients and servers. It provides an easy-to-use API, and it handles a variety of real-time transports, including WebSocket, with automatic fallbacks for clients that don't support WebSocket natively. Socket.IO also takes care of connection handling, message encoding/decoding, and event-based communication.

Here's an example of how to use Socket.IO on the client side:

1. First, you need to include the Socket.IO library in your HTML file:

```html
<script src=https://cdn.socket.io/4.4.1/socket.io.min.js integrity=sha384-KxeohWd8o8C+bVtM7mOcwCzg37O9ffyabzTAn00GaxZLfF8fHrYpnikV7Df0ij33 crossorigin=anonymous></script>
```

2. Then, you can create a connection to the server and listen for events using JavaScript:

```javascript
const socket = io('http://your-backend-server.com:3000');

socket.on('connect', () => {
  console.log('Connected to the server');

  // Example of sending a message to the server
  socket.emit('myEvent', { data: 'Hello, server!' });
});

// Example of listening for an event from the server
socket.on('anotherEvent', (data) => {
  console.log('Received data:', data);
});

socket.on('disconnect', () => {
  console.log('Disconnected from the server');
});
```

Socket.IO provides a high level of abstraction, allowing you to focus on the logic of your game client while it handles the underlying WebSocket communication. However, if you need to work with raw WebSockets, you can use the built-in WebSocket API in modern browsers, though it will require more manual connection and message handling.
