For loops in strings

Consider the following example, we are iterating over a string

import (
	"fmt"
	"reflect"
)

func main() {
	str := "hello world"
	for i := 0; i < len(str); i++ {
		element := str[i]
		fmt.Print(element, " ")
		fmt.Println(reflect.TypeOf(element))
	}
}

104 uint8

The value str[i] actually return a byte of uint8, or a rune

To convert a byte to a string

string(var)

To convert a byte array to string

string(byteArray)
