  Sure thing! Here's how you can use websocket in JavaScript to receive live cryptocurrency prices: 1. Start by creating a new WebSocket object and passing the websocket URL as a parameter. 2. Set up event listeners for the websocket events such as onopen, onmessage, onerror, and onclose. 3. In the onopen event listener, send a message to the server to subscribe to the cryptocurrency price updates. 4. In the onmessage event listener, parse the received data and update your UI with the latest cryptocurrency prices. 5. Handle any errors or connection closures in the onerror and onclose event listeners. Here's a code snippet to help you get started: ```javascript const socket = new WebSocket('wss://example.com/ws'); socket.onopen = function(event) { socket.send('subscribe prices'); }; socket.onmessage = function(event) { const data = JSON.parse(event.data); // Update UI with the received cryptocurrency prices }; socket.onerror = function(error) { console.error('WebSocket error:', error); }; socket.onclose = function(event) { console.log('WebSocket closed:', event); }; ``` With this implementation, you'll be able to receive live cryptocurrency prices using websocket in JavaScript. Good luck!
