  Sure thing! Using JavaScript's map function is a great way to display real-time cryptocurrency prices. First, you'll need to create an array of cryptocurrency symbols. Then, you can use the map function to iterate over this array and fetch the prices for each symbol from a cryptocurrency API. Finally, you can display the prices on your web page. Here's a code snippet to get you started: const symbols = ['BTC', 'ETH', 'XRP']; const prices = symbols.map(symbol => { // Fetch price for each symbol from API const price = fetchPriceFromAPI(symbol); return price; }); // Display prices on web page prices.forEach(price => { const priceElement = document.createElement('p'); priceElement.textContent = price; document.body.appendChild(priceElement); }); I hope this helps! If you have any more questions, feel free to ask.
