        this.name = name;
    }
    speak() {
        console.log(`${this.name} makes a noise.`);
    }
}

class Dog extends Animal {
    speak() {
        console.log(`${this.name} barks.`);
    }
}

const dog = new Dog('Rex');
 dog.speak(); // Rex barks.

What are the benefits of using class inheritance?

The benefits include code reuse, easier maintenance, and a clearer structure for your code, making it more understandable.
