How To Use JavaScript Class Decorators? Are you interested in enhancing your JavaScript skills and writing more modular, maintainable code? In this detailed video, we explore how to utilize class decorators in JavaScript to add new features or modify existing classes seamlessly. We’ll explain what class decorators are and how they work as functions that can alter or replace classes during their creation. You’ll learn how to apply decorators using the @ syntax and see practical examples like sealing classes to prevent modifications and logging method calls for better debugging.

Additionally, we cover how to use decorator factories to pass parameters into your decorators, making them more flexible and reusable. You’ll see how stacking multiple decorators can be done effectively, and understand the importance of their evaluation order. Since decorators are still a proposal in JavaScript, we also discuss the tools needed, such as Babel or TypeScript, to implement them in real-world projects. TypeScript’s additional features for decorators are also highlighted to help you get the most out of this powerful pattern.

Whether you’re a beginner or an experienced developer, mastering decorators can make your code cleaner and more organized. Join us to learn how to leverage decorators for logging, registration, and behavior modifications without altering your core class code.
