Handling Radio buttons

Getting Help
1

Hi,

I saw this code here Validation of inputs · Build web application with Golang for handling radio button input from forms.

I don’t understand how it works.

slice:=int{1,2}

for _, v := range slice {
if v == r.Form.Get(“gender”) {
return true
}
}
return false

The first line creates a slice named “slice”.
The for loop iterates over the slice and compares each element of the slice against the value returned by r.Form.Get("gender"). If both are equal, the loop exits immediately by returning true.
Else the function returns false after the loop.
