const toMinMaxWith: <Value>(fn) => OptionalReducer<MinMax<Value>>

Defined in: statistics.d.ts:934

Returns an optional reducer that finds the MinMax value of the values it receives by comparing the numerical values of each value, as defined by fn.

Parameters

fn

(value) => number

Returns

Example

console.log(
  pipe(
    [`sloth`, `more sloth`, `sleep`, `some sloth`],
    map(string => [string.length, string]),
    reduce(toGrouped(toMinMaxWith(string => string.codePointAt(0)), toMap())),
  ),
)
//=> Map(2) {
//=>   5 => { min: 'sloth', max: 'sloth' },
//=>   10 => { min: 'more sloth', max: 'some sloth' }
//=> }
