Map

func Map[T any, R any](slice []T, mapper func(value T, index int, slice []T) R) (mapped []R)

Map allows transforming the values in a slice by executing the given mapper function for each element in the slice. The function is passed the current element, the current index and the slice itself as function arguments.

func main() {
    numerals := []int{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

    result := sliceutils.Map(numerals, func(value int, index int, slice []int) int {
        return value * 2
    })

    fmt.Print(result) // [0, 2, 4, 6, 8, 10, 12, 14, 16, 18]
