⚙️ Przeciążanie operatorów

Klasy mogą definiować własne zachowanie dla operatorów.

Przykład: Vector

class Vector {
    init(x, y) {
        this.x = x;
        this.y = y;
    }

    operator +(other) {
        return Vector(this.x + other.x, this.y + other.y);
    }

    operator -(other) {
        return Vector(this.x - other.x, this.y - other.y);
    }

    operator *(scalar) {
        return Vector(this.x * scalar, this.y * scalar);
    }

    operator ==(other) {
        return this.x == other.x && this.y == other.y;
    }
}

let v1 = Vector(1, 2);
let v2 = Vector(3, 4);

let sum = v1 + v2;       // Vector(4, 6)
let scaled = v1 * 3;    // Vector(3, 6)
print(v1 == v2);        // false
