StaticallArray of promise-like values to be wait for
an array of PromiseRejectedResult with all the rejected promises, if any
Comparison with other similar Promise methods:
Promise.all: This has an "all-or-nothing" behavior. As long as one of the promises is rejected, the result is
rejected. More importantly, it does not wait for al the promises to finish, which could lead to undesired behaviorsPromise.allSettled: This method waits for all the promises to finish and then returns an array of results. Some
of them will be fulfilled and some rejected. More importantly, it never throws an error, which could lead to
unexpected consequences. For example if you do "await Promise.allSettle(...)" expecting it to throw if some of them
failed, you won't get that.In brief, Promises.allSettledAndFulfilled behaves exactly the same way as Promise.allSettle but it throws with
an array of the failed promises, only if there are any.
Waits until all the passed promise-like values are settled, no matter if they were fulfilled or rejected. If some rejected were found, an array with all the rejected promises is thrown. If all were fulfilled, an array of PromiseFulfilledResult is returned
