try/catch/finally

try {
    let result = riskyOperation();
} catch (e) {
    print("Error: " + e.message);
    print("Line: " + e.line);
} finally {
    print("Cleanup");  // Zawsze się wykona
}
        

throw

fn divide(a, b) {
    if (b == 0) {
        throw "Division by zero!";
    }
    return a / b;
}

// Można rzucić obiekt
throw {message: "Custom error", code: 500};
        

ensure (runtime type check)

let age = 25;
ensure age is number;  // OK

let name = "Alice";
ensure name is string;  // OK
