  One of the best practices for displaying real-time cryptocurrency prices on a website using JavaScript is to utilize WebSocket technology. By establishing a WebSocket connection with a cryptocurrency exchange's API, you can receive live price updates and display them on your website in real-time. This allows your users to stay up-to-date with the latest prices without the need for manual refreshing. Additionally, you can implement features such as price alerts or real-time charts to enhance the user experience. Make sure to handle errors and implement proper error handling mechanisms to ensure the stability and reliability of your real-time price updates.

  When it comes to displaying real-time cryptocurrency prices on a website using JavaScript, it's important to consider the performance impact. Fetching price updates too frequently can put a strain on the user's device and consume excessive bandwidth. To mitigate this, you can implement throttling mechanisms to limit the frequency of price updates, such as debouncing or throttling functions. Another best practice is to cache the fetched price data on the client-side to reduce the number of API calls and improve performance. Remember to handle cases where the WebSocket connection is lost or the API is temporarily unavailable to provide a seamless user experience.
