What Is The 'extends' Keyword In JavaScript Classes? Are you interested in learning how to create more organized and efficient JavaScript code? In this video, we’ll explore the 'extends' keyword and how it helps in building class hierarchies in JavaScript. We’ll start by explaining what inheritance means in object-oriented programming and how the 'extends' keyword makes it simple to reuse code across different classes. You’ll learn how subclasses can inherit properties and methods from parent classes, allowing you to create more specific and versatile objects. We’ll also cover important concepts like calling the super function inside constructors to ensure proper initialization of subclasses, as well as how to override methods for customized behavior.

This technique is especially useful when designing real-world models, such as animals, vehicles, or business entities, where different objects share common features but also have unique traits. Additionally, we’ll discuss how inheritance contributes to code flexibility through polymorphism, making your programs easier to maintain and extend. By mastering the 'extends' keyword, you’ll be able to write cleaner, more efficient code that reflects complex relationships naturally. Whether you’re a beginner or looking to strengthen your JavaScript skills, understanding class inheritance is essential for developing powerful web applications.
