API
pReduce(input, reducer, initialValue?)
Returns a Promise that is fulfilled when all promises in input and ones returned from reducer are fulfilled, or rejects if any of the promises reject. The fulfilled value is the result of the reduction.
input
Type: Iterable<Promise|any>
Iterated over serially in the reducer function.
reducer(previousValue, currentValue, index)
Type: Function
Expected to return a value. If a Promise is returned, it's awaited before continuing with the next iteration.
initialValue
Type: unknown
Value to use as previousValue in the first reducer invocation.
