Reduce

Reduce combine a list of values into a single value. acc is the initial state, and each successive step of it should be returned by the reduction function.

package main

import (
 "fmt"
 u "github.com/rjNemo/underscore"
)

func main() {
 nums := []int{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
 sum := func(n, acc int) int { return n + acc }
 fmt.Println(u.Reduce(nums, sum, 0)) // 45
}
