Function reduceAsync

Similar to Array.reduce, but works on async iterables and the accumulator can return a Promise.

Param: values

The iterable or async iterable to be reduced.

Param: accumulator

A callback to be called for each value. If it returns null or undefined, the previous result will be kept.

Param: init

The initial value.

Returns

The accumulated result.

reduceAsync<T>(
    values: Iterable<T, any, any> | AsyncIterable<T, any, any>,
    accumulator: (
        a: T,
        b: T,
        i: number,
    ) => undefined | null | void | T | Promise<undefined | null | void | T>,
): Promise<T>
