func Map 

func Map[T any, T2 any](s []T, fn func(t T) (T2, error)) (t2 []T2, err error)

Calls a defined callback function on each element of an array, and returns an array that contains the results. 

func StringArrayToNumberArray() {
	var stringArray []string = []string{"1", "2", "3"}

	numberArray, err := Map(stringArray, func(s string) (int64, error) {
		return strconv.ParseInt(s, 10, 64)
	})
	if err != nil {
		fmt.Println("string array to number array error, msg: ", err)
		return
	}
	fmt.Println(numberArray)
}

func CalculateSquareValue() {
	var numArray []int64 = []int64{2, 3, 4}
	squareArray, _ := Map(numArray, func(n int64) (int64, error) {

fileBytes, err := gm.ReadFileBytes("example.go")
if err != nil {
	fmt.Printf("read file bytes err, msg: %v\n", err)
	return
}

hash, err := gm.ReadFileHash(fileBytes)
if err != nil {
	fmt.Printf("read file hash err, msg: %v\n", err)
	return
}
fmt.Printf("hash: %v\n", hash)
