Skip first element of an array in Golang

Question

I have the following code segments

for _, val := range Arr {
    // something have to do with val
}

In Arr , there might be more than 1 elements. I want to skip the first element of Arr and continue the loop from the second element.

For example if Arr contains {1,2,3,4}. With the query I just want to take {2,3,4}.

Is there a way to do that with the range query ?

Answer 1

Yes. Use this

for _, val := range Arr[1:] {
// something to do with val
}

Or in case you can get empty slice:

for i := 1; i < len(Arr); i++ {
// something to do with Arr[i]
}

Answer 2

Use a standard for loop or the slice operator:

for _, val := range Arr[1:] {
    // Do something
}

// Or
for i := 1; i < len(Arr); i++ {
    val = Arr[i]
    // Do something
}
