bookOverriding Methods in Subclasses

When working with classes in JavaScript, you often want subclasses to behave differently from their parent classes in certain situations. Method overriding allows you to redefine a method in a subclass, providing specialized behavior while keeping the same method name. This is a key feature of object-oriented programming and helps you create flexible and reusable code structures. By overriding a method, the subclass version is called instead of the parent's version when you use that method on an instance of the subclass. This is especially useful when the subclass represents a more specific concept that needs to act differently from the general parent class.

class Animal { speak() { console.log("The animal makes a sound."); } } class Dog extends Animal { speak() { console.log("The dog barks."); } } const genericAnimal = new Animal(); genericAnimal.speak(); // The animal makes a sound. const myDog = new Dog(); myDog.speak(); // The dog barks.
