  One of the best ways to display real-time cryptocurrency prices in JavaScript is by using WebSocket connections. WebSocket allows for bidirectional communication between the client and the server, making it ideal for real-time updates. You can subscribe to a cryptocurrency exchange's WebSocket API and receive price updates as they happen. There are also JavaScript libraries like Socket.io that simplify WebSocket implementation. With WebSocket, you can ensure that the prices are updated instantly without the need for constant polling.

  If you prefer a simpler approach without dealing with WebSocket connections, you can use AJAX requests to periodically fetch the latest prices from a cryptocurrency exchange's API. You can set up a timer to send requests at regular intervals and update the prices on your website accordingly. However, keep in mind that this method may introduce a slight delay in displaying the latest prices, as it depends on the frequency of your AJAX requests. Additionally, make sure to handle any rate limits imposed by the exchange's API to avoid getting blocked.
