        Type Parameters

        • A extends [] | readonly unknown[]

        Parameters

        • collection: A

        Returns Promise<{
            -readonly [K in keyof A]: SettleResult<Awaited<A[K]>>
        }>

  • any: (<T>(iterable) => Promise<T>)
      • <T>(iterable): Promise<T>

      • Promise.any implementation

        just ref the MDN document

        Promise.any() takes an iterable of Promise objects and, as soon as one of the promises in the iterable fulfils, returns a single promise that resolves with the value from that promise. If no promises in the iterable fulfil (if all of the given promises are rejected), then throw the array of errors
