Go Switch

I like switch in Go.

func main() {
    all := []string{"Denver", "London", "NY", "SF"}

    for _, city := range all {
        switch city {
        case "Denver":
            // code for Denver
            fmt.Println("Denver")
        case "London", "SF": // London OR SF the same logic
            // code for London/SF
            fmt.Println("London/SF")
        case "NY":
            // code for NY
            fmt.Println("NY")
        default:
            // code default
            fmt.Println("default")
        }
    }
}

Very easy to use, we just create cases and what to do by default:
