golang for loop string in slice code example

Example 1: golang loop through array

arr := []int{1, 2, 3, 4, 5}
//using range 
for index, ele := range arr { // you can escape index by _ keyword
	fmt.Println(index, ele)
}

Example 2: go iterate over slice

nums := []int{2, 3, 4}
    sum := 0
    for _, num := range nums {
        sum += num
    }
    fmt.Println("sum:", sum)
