Homework!

As you read through this, notice the new content introduced. We encourage you to do your own research (this can be Google, ChatGPT, documentation, etc.). Here, we introduce the _ property (memory safety), extends keyword, and super() method.

To complete the homework, implement the TODO: comments. The example usage should guide you and work if all implementation is done correctly. Have fun!

If anything simply cannot go wrong, it will anyway.

class Aircraft {
    // Constructor
    constructor(model, capacity, range) {
        this._model = model;
        this._capacity = capacity;
        this._range = range;
    }

    // Getter for model
    get model() {
        return this._model;
    }

    // Setter for model
    set model(newModel) {
        this._model = newModel;
    }

    // Getter for capacity

        return this._capacity;
    }

    // Setter for capacity
    set capacity(newCapacity) {
        this._capacity = newCapacity;

    }

    // Static method to compare range
    static compareRange(aircraft1, aircraft2) {
        return aircraft1.range - aircraft2.range;

// Example usage
let boeing = new Aircraft('Boeing 747', 416, 13800);
let airbus = new Aircraft('Airbus A380', 853, 15700);

console.log(boeing.displayDetails());
console.log(airbus.displayDetails());
console.log(`Range difference: ${Aircraft.compareRange(boeing, airbus)} km`);

// FighterJet class extending Aircraft

    constructor(model, capacity, range, speed) {
        super(model, capacity, range);
        this._speed = speed;
    }

    // Getter for speed

    // Method to display fighter jet details
    displayDetails() {
        return `Model: ${this._model}, Capacity: ${this._capacity}, Range: ${this._range} km, Speed: ${this._speed} km/h`;
    }
}

// Example usage
let f16 = new FighterJet('F-16', 1, 4220, 2400);
let f22 = new FighterJet('F-22', 1, 2960, 2410);

console.log(f16.displayDetails());
console.log(f22.displayDetails());
console.log(`Range difference: ${Aircraft.compareRange(f16, f22)} km`);

If you perceive that there are four possible ways in which a procedure can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop.

You have no purpose because you fear to seek one. That fear is your failure. Your fear brings you pain. We know pain. Our purpose is its end.
