What is inheritance in JavaScript classes?

Inheritance in JavaScript 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! You can use the extends keyword. For example:

class Animal {
  speak() {
    console.log('Animal speaks');
  }
}

class Dog extends Animal {
  speak() {
    console.log('Dog barks');
  }
}

const dog = new Dog();
dog.speak(); // Output: Dog barks

What are the benefits of using inheritance?

Inheritance helps in organizing code, reducing redundancy, and creating a clear hierarchy among classes.

Are there any drawbacks to using inheritance?

Yes, it can lead to tight coupling between classes and make the code harder to maintain if overused.
