Control Commands

Control Structors (if/else/switch)

if command

switch

Syntax:

    switch <variable> {
        case <value>:
            // some code
        case <value2> 
            // some other code
        default: 
            // some code that runs if the others do not.
    }

the switch command allows one of many conditionals to be selected based on the “switch”. In the simple and probably most commong example switch command takes a single parameter and based on it does one of many cases.

simple example:

 	

    i := 2
    fmt.Print("Write ", i, " as ")
    switch i {
    case 1:
        fmt.Println("one")
    case 2:
        fmt.Println("two")
    case 3:
        fmt.Println("three")
    }

example: (from: https://gobyexample.com/switch)

switch time.Now().Weekday() {
    case time.Saturday, time.Sunday:
        fmt.Println("It's the weekend")
    default:
        fmt.Println("It's a weekday")
    }
