 // sequentially get data from API while waiting for previous call to finish
 for (let temp of arr) {
        const res = await fetch('https://jsonplaceholder.typicode.com/users/' + temp).then(res => res.json()).then(res => res);
 }
// sequentially get data from API asynchronously
const promises = Array(10).fill(null).map((item, index) => fetch(`https://jsonplaceholder.typicode.com/users/${index + 1}`).then(res => res.json()).then(res => res));
  for await (const item of promises) {
