Function reduce

reduce<T>(reducer: ((accumulator: T, currentValue: T) => T), iterable: Iterable<T> | AsyncIterable<T>): Promise<T>
Reduces an iterable to a single value by applying the provided reducer function against an accumulator and each element yielded by the iterable (in the order in which they are received).

The first invocation of the reducer will receive the first value yielded by the underlying iterable as its accumulator and the second value yielded as its currentValue argument.

reduce<T, R>(reducer: ((accumulator: R, currentValue: T) => R), initialValue: R, iterable: Iterable<T> | AsyncIterable<T>): Promise<R>
Reduces an iterable to a single value by applying the provided reducer function against an accumulator and each element yielded by the iterable (in the order in which they are received).
