async/await is great but avoid going too sequential

sequential-promises.js

// Not recommended - too sequential
async function logInOrder(urls) {
  for (const url of urls) {
    const response = await fetch(url);
    console.log(await response.text());
  }
}

// Recommended - nice and parallel
async function logInOrder(urls) {
  // fetch all the URLs in parallel
  const textPromises = urls.map(async url => {
    const response = await fetch(url);
    return response.text();
  });

  // log them in sequence
  for (const textPromise of textPromises) {
    console.log(await textPromise);
  }
}
