I wrote a few mini functions to convert and support with go lang

go_ultilities.go

package main

import (
	"fmt"
	"reflect"
)

func main() {
	checkType()
}

func checkType() {
	// Using "reflect" function to check type
	var x = "this's string"
	var y = 12345

	if reflect.TypeOf(x).Kind() == reflect.String {
		fmt.Printf("%T: %v \n", x, x)
	}

	if reflect.TypeOf(y).Kind() == reflect.Int {
		fmt.Printf("%T: %v \n", y, y)
	}

}

func removeLastString(str string) string {
	if len(str) > 0 && str != "" {
		return str[:len(str)-1]
	}
	return str
}
