What potential issue exists with this code in an async function?
for (let i = 0; i < urls.length; i++) {
const data = await fetch(urls[i]);
console.log(data);
}
This code processes requests sequentially, which may not be optimal: 1) Each iteration waits for the previous request to complete, 2) Total time is the sum of all request times, 3) Could be slower than parallel processing, 4) Better to use Promise.all() with map() for parallel requests, 5) Sequential processing might be desired for rate limiting or dependent operations, 6) Performance impact increases with the number of URLs.
