promises-complete.js

const PromiseArray = [
  Promise.resolve(100),
  Promise.reject(null),
  Promise.resolve("Data release"),
  Promise.reject(new Error('Something went wrong'))];

Promise.all(PromiseArray)
  .then(data => console.log('all resolved! here are the resolve values:', data))
  .catch(err => console.log('got rejected! reason:', err))

// If you want to wait until all your promises are complete, regardless whether they get rejected or resolved.

const PromiseArray = [
  Promise.resolve(100),
  Promise.reject(null),
  Promise.resolve("Data release"),
  Promise.reject(new Error('Something went wrong'))];

Promise.allSettled(PromiseArray)
  .then(res => {
    console.log(res);
  })
  .catch(err => console.log(err));
//[
//{status: "fulfilled", value: 100},
//{status: "rejected", reason: null},
//{status: "fulfilled", value: "Data release"},
//{status: "rejected", reason: Error: Something went wrong ...}
//]
