Please check out the examples to see how to use the library.

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

func main() {
 numbers := []int{1, 2, 3, 4, 5, 6, 7, 8, 9}
 // filter even numbers from the slice
 evens := u.Filter(numbers, func(n int) bool { return n%2 == 0 })
 // square every number in the slice
 squares := u.Map(evens, func(n int) int { return n * n })
 // reduce to the sum
 res := u.Reduce(squares, func(n, acc int) int { return n + acc }, 0)

 fmt.Println(res) // 120
}
