# promise-settled-aggregate

> Await an array of promises to be settled, then reject with an AggregateError upon failure, or resolve with an array of values upon success.

It works like [Promise.allSettled](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/allSettled) except it will reject with an [AggregateError](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/AggregateError) if some of the promises are rejected, otherwise it resolves with the fulfilled values like [Promise.all](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/all).

```js

try {

  const [a, b, c, d] = await promiseSettledAggregate([

    Promise.reject(new Error("Boom")),

    Promise.resolve(2),

    Promise.resolve(true),

    Promise.reject(new Error("Pow")),

  ]);

} catch (err) {

  err.errors.forEach(console.error);

}

```
