promise-settled-aggregate/README.md

Works like Promise.allSettled except it will reject with an AggregateError if some of the promises rejected, otherwise resolves with the fulfilled values.

# 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);
}
```
