Inheritance with extends

Create subclasses

Use extends to create a subclass that inherits from a parent class.

class Animal {
  speak() {
    console.log("Some sound");
  }
}

class Dog extends Animal {
  speak() {
    console.log("Woof!");
  }
}

const dog = new Dog();
dog.speak(); // "Woof!"

The subclass inherits methods and can override them.
