Conditions, loops and switches

In ColaScript switch statement may be used without argument:

switch {
    when score < 60: 'F';
    when score < 70: 'D';
    when score < 80: 'C';
    when score < 90: 'B';
    default: 'A';
}

As you see, you can use keyword when, it's like case, but if the condition is satisfied, switch will break'ed.

Also you can use as expression if condition:

String name = 
    if (sex == "male") "Dan" 
    else if (sex == "female") "Dasha" 
    else "none";

and switch statement:

String grade = switch {
    when score < 60: 'F';
    when score < 70: 'D';
    when score < 80: 'C';
    when score < 90: 'B';
    default: 'A';
};

Also available ES6 for ...of loop:

for _ of [5...10] {
    console.log(_);
}

As you can see for (as well as if, while and switch) may used without brackets (also you can use old syntax).
