We can use multiple values inside a single case block. In such case, the case block is executed if the expression matches with one of the case values.
Example:
dayOfWeek := 6
switch dayOfWeek {
case 6,7:
fmt.Println("Weekend")
case 1,2,3,4,5:
fmt.Println("Weekday")
default:
fmt.Println("Invalid day")
}
