Market Prices

The JavaScript code starts with selecting the HTML element with the id of priceTable, which represents the <tbody> element in the table where the asset prices will be displayed.

The fetchPrices() function is defined to fetch the prices for cryptocurrencies and metals.

The cryptoUrl variable holds the URL for fetching cryptocurrency prices from the CoinCap API. The metalsUrl variable holds the URL for fetching metal prices from the Metals API. You need to replace 'YOUR_API_KEY' in the metalsUrl with your actual API key.

The fetch(cryptoUrl) fetches the cryptocurrency prices and processes the response by converting it to JSON format. It then loops through the data and creates table rows dynamically to display the name, price, and 24-hour change percentage for each cryptocurrency.

The fetch(metalsUrl) fetches the metal prices and processes the response by converting it to JSON format. It uses Object.entries() to iterate over the rates of different metals and creates table rows dynamically to display the metal symbol, price, and a placeholder for the change information.

The fetchPrices() function is called initially to fetch the prices when the program starts.

The prices are then refreshed every 5 seconds using setInterval(fetchPrices, 5000) to keep them up to date.
