  To track cryptocurrency prices in real-time using JavaScript, you can make use of APIs provided by cryptocurrency exchanges. These APIs allow you to fetch real-time price data for different cryptocurrencies. You can use JavaScript's fetch() method to make HTTP requests to these APIs and retrieve the price data. Once you have the data, you can update it on your website or application using JavaScript's DOM manipulation methods. This way, you can display the latest cryptocurrency prices to your users in real-time.

  Real-time cryptocurrency price tracking with JavaScript is a popular use case for many developers. One approach is to use WebSocket connections to cryptocurrency exchanges. By establishing a WebSocket connection, you can receive real-time updates on cryptocurrency prices without the need to constantly make API requests. This approach is more efficient and provides faster updates compared to traditional API polling. There are libraries available, such as Socket.IO, that simplify the process of establishing WebSocket connections and handling real-time data updates.
