Example 1
const red = AsyncReducer.combineObj({
theSum: Reducer.sum,
theAverage: Reducer.average
});
await AsyncStream.from(Stream.range({ amount: 9 }))
.reduce(red));
// => { theSum: 36, theAverage: 4 }
Parameters
reducerObj: readonly [K in keyof R]: AsyncReducer<T, R[K]> & Record<string, AsyncReducer<T, unknown>>
- an object of keys, and reducers corresponding to those keys
