_Underscore
underscore is a Go library providing useful functional programming helpers without
extending any built-in objects.
It is mostly a port from the underscore.js library based on generics available
from go1.18.
Install the library using
go get github.com/rjNemo/underscore
Please check out the examples to see how to use the library.
package main
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
}
