Tip 39: Extend Existing Prototypes with Class
Explore how JavaScript classes relate to prototypes and learn to extend existing prototypes using class syntax. Understand the difference between JavaScript's prototype-based inheritance and traditional object-oriented models to better integrate modern features with legacy code and avoid subtle bugs.
Now that you know how to write classes in JavaScript, it’s time to see how the new class syntax relates to JavaScript prototypes. It’s important to understand that classes in JavaScript and prototypes aren’t different. Classes are just a clean way to write regular JavaScript. By understanding how classes in JavaScript differ from traditional object-oriented languages, you’ll be able to integrate new syntax with legacy code and prevent subtle bugs from surfacing.
