JavaScript

Async Await concurrent execution of promises. Avoid sequencing async() await operations as they are not concurrent and the performance of your app will decrease.

1// Sample Example
2const sendRequest = (item) => {
3     // do stuff
4     return new Promise((resolve, reject) => {
5          resolve();
6     });
7});

9async function processItems() {
10  const items = await getItems()    // async call
11  const promises = items.map((item) => sendRequest(item))
12  await Promise.all(promises)    // async call
13}
14
15processItems()
16.then((result) => {
