When Statement

When statements can be used as an alternative to if-else ladder. Each case takes in an conditional expression, and is executed if they are truthy. The else case is invoked if none evaluates to a truthy value. Atmost one case is executed.

Syntax

when {
    expr1: statement1
    expr2: statement2
    ...
    exprN: statementN
    else: elseStatement
}

Example

a := 2;
b := 3;
when {
    a > b: {
        print("Yes");
    }
    else: print("No");
}

# prints "No"
