What is inheritance in ES6 classes?

Inheritance in ES6 classes allows one class to inherit properties and methods from another, promoting code reuse.

Can you give me an example of how to implement inheritance?

Sure! Here's a simple example:

class Animal {
    constructor(name) {
        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 inheritance?

Inheritance helps in reducing code duplication, making it easier to maintain and extend code. It also promotes a clear hierarchy.

Are there any drawbacks to using inheritance?

Yes, excessive use of inheritance can lead to complex hierarchies and make the code harder to understand. Composition is often preferred.
