variable Reducer.minBy

import { Reducer } from "https://deno.land/x/rimbu@0.13.1/mod.ts";
const { minBy } = Reducer;

Returns a Reducer that remembers the minimum value of the inputs using the given compFun to compare input values

Examples

Example 1

const stream = Stream.of('abc', 'a', 'abcde', 'ab')
console.log(stream.minBy((s1, s2) => s1.length - s2.length))
// 'a'

type
