Await all promises in array

awaitPromiseArr.js

/*
// without response:
for await (async of promises) {}
  
// with response:
for await (const resp of promises) {
  console.log(resp); // same as: const resp = await promise;
}
*/


// example:

const promise1 = new Promise(resolve => { window.setTimeout(() => { resolve('test') }, 1000); });
const promise2 = new Promise(resolve => { resolve('test2') });

const promises = [promise1, promise2];

(async function () {
  window.setTimeout(async () => { 
    for await (async of promises) {
      console.log("promise resolved");
    }
    console.log("all promises resolved!");
  }, 2000);
})();
