Promise.any and AggregateError
Promise.any() accepts an iterable of promises and returns a promise that is fulfilled by the first given promise to be fulfilled, or rejected with an AggregateError holding the rejection reasons if all of the given promises are rejected. AggregateError is a support class that aggregates one or more errors into a single object.
This rounds out standard JS support for commonly available Promise combinators already available in userland libraries.
