Function: toMultiple()
Returns a Reducer or OptionalReducer that reduces values to
an object or array of the same shape as reducers using all of the reducers
in reducers.
Returns an OptionalReducer if at least one of the input reducers is an OptionalReducer. Otherwise, returns a Reducer.
Example
console.log(
pipe(
[`sloth`, `some sloth`, `sleep`, `more sloth`, `even more sloth`],
map(string => string.length),
reduce(toMultiple([toSet(), toCount(), toJoin(`,`)])),
),
)
//=> [ Set(3) { 5, 10, 15 }, 5, '5,10,5,10,15' ]
console.log(
pipe(
[`sloth`, `some sloth`, `sleep`, `more sloth`, `even more sloth`],
map(string => string.length),
reduce(
toMultiple({
set: toSet(),
count: toCount(),
string: toJoin(`,`),
}),
),
),
)
//=> { set: Set(3) { 5, 10, 15 }, count: 5, string: '5,10,5,10,15' }
