Variables & Types

// English - Basic Example
// Basic example with native keywords

let x = 10;
let y = 20;
let sum = x + y;

print(sum);

// English - Arrays
// Arrays with native keywords

// Create arrays
let numbers = [1, 2, 3, 4, 5];
let names = ["Alice", "Bob", "Charlie"];

// Access elements
let first = numbers[0];
let second = numbers[1];

// Empty array
let list = [];

// English - Object-Oriented Programming (OOP)
// Object-based programming patterns in HudHudScript

// ============================================
// 1. Basic Object Definition
// ============================================

object Animal {
    name: "Unknown",
    species: "Unknown",
    age: 0,
    alive: true
}

object Cat {
    name: "Whiskers",
    species: "Cat",
    age: 3,
    alive: true,
    color: "orange",
    indoor: true
}

print("=== Basic Objects ===");
print(Animal.name);
print(Cat.name + " (" + Cat.species + ") - " + Cat.age + " years old");

// ============================================
// 2. Factory Functions (Constructor Pattern)
// ============================================

function CreateCar(brand, model, year, color) {
    return {
        brand: brand,
        model: model,
        year: year,
        color: color,
        mileage: 0,
        running: true
    };
}

let car1 = CreateCar("Toyota", "Corolla", 2024, "white");
let car2 = CreateCar("Honda", "Civic", 2023, "black");

print("\n=== Factory Functions ===");
print(car1.brand + " " + car1.model + " - " + car1.color);
print(car2.brand + " " + car2.model + " - " + car2.color);

// ============================================
// 3. Behavior Functions (Method Pattern)
// ============================================

function car_info(car) {
    return car.brand + " " + car.model + " (" + car.year + ") " + car.color;
}

function drive(car, distance) {
    let new_km = car.mileage + distance;
    print(car.brand + " drove " + distance + " km. Total: " + new_km + " km");
    return new_km;
}

function car_age(car) {
    return 2024 - car.year;
}

print("\n=== Behavior Functions ===");
print(car_info(car1));
drive(car1, 150);
drive(car1, 230);
print("Car age: " + car_age(car1) + " years");

// ============================================
// 4. Object Composition
// ============================================

function CreateAddress(city, district, neighborhood) {
    return {
        city: city,
        district: district,
        neighborhood: neighborhood
    };
}

function CreatePerson(name, age, address) {
    return {
        name: name,
        age: age,
        address: address,
        occupation: "Not specified"
    };
}

let home_addr = CreateAddress("London", "Camden", "Primrose Hill");
let person = CreatePerson("Alice", 28, home_addr);

print("\n=== Object Composition ===");
print(person.name + " - " + person.age + " years old");
print("Address: " + person.address.neighborhood + ", " + person.address.district + "/" + person.address.city);

// ============================================
// 5. Collections and Object Arrays
// ============================================

let students = [
    CreatePerson("Bob", 20, CreateAddress("New York", "Manhattan", "SoHo")),
    CreatePerson("Charlie", 22, CreateAddress("San Francisco", "Mission", "Valencia")),
    CreatePerson("Diana", 21, CreateAddress("Chicago", "Lincoln Park", "DePaul"))
];

print("\n=== Object Collections ===");
let idx = 0;
while (idx < 3) {
    let student = students[idx];
    print(student.name + " - " + student.address.city);
    idx = idx + 1;
}

// ============================================
// 6. Business Logic Object (Shopping Cart)
// ============================================

function CreateCartItem(product, price, quantity) {
    return {
        product: product,
        price: price,
        quantity: quantity
    };
}

function item_total(item) {
    return item.price * item.quantity;
}

let cart = [
    CreateCartItem("Laptop", 1200, 1),
    CreateCartItem("Mouse", 25, 2),
    CreateCartItem("Keyboard", 75, 1)
];

print("\n=== Shopping Cart ===");
let grand_total = 0;
let s = 0;
while (s < 3) {
    let item = cart[s];
    let total = item_total(item);
    print(item.product + " x" + item.quantity + " = $" + total);
    grand_total = grand_total + total;
    s = s + 1;
}
print("Grand Total: $" + grand_total);
