Range Index Only

Ignoring values

If you only need the index, you can omit the value variable:

nums := []int{10, 20, 30}
for i := range nums {
    fmt.Println(i)
}

This prints $0$ , $1$ , $2$ . When you don't assign the second variable, Go only gives you the index. This is cleaner than using the blank identifier.
