If / But If / Else

GS uses if, but if (instead of else if), and else:

{
    fnc main {
    umur = 20

    if umur >= 18 {
             print("dewasa")
        } but if umur >= 13 {
             print("remaja")
        } else {
             print("anak-anak")
        }
   }
}

For Loops

GS has a single for ... in loop form, commonly paired with range():

{
    fnc main {
       for i in range(5) {
           print(i)
        }
    }
}

You can also iterate directly over a list:

{
    fnc main {
        angka = [10, 20, 30]
        
        for n in angka {
            print(n)
       }
    }
}

Break and Continue

{
     fnc main {
         for i in range(10) {
             if i == 5 {
               break
             }
             print(i)
         }
    }
}

Match

match compares a value against a list of cases:

{
    fnc main {
        umur = 18

     match umur {
           18) print("pas 18 tahun")
           20) print("pas 20 tahun")
        }
   }
}
