Nice article. You could make it better by inlining more examples like you have in #4. Keep going!

Proxy-based reactivity, like in the example above, has one little issue: effects are baked in, so hardly reusable and testable, which ultimately means lower-quality code.

If you then try to expose or separate those effects out, don't you end up reinventing... the observable?

Great insights! JavaScript is evolving rapidly, and these patterns will definitely play a major role in writing cleaner and more efficient code. Pattern Matching and Proxy-Based Observables seem especially promising for improving state management and reducing unnecessary re-renders in modern applications.

For developers looking to create website projects with scalable and maintainable architecture, embracing these modern JavaScript patterns early on can make a huge difference. Modular Federation, for example, is a game-changer for large-scale applications with independent teams.

Which of these patterns do you think will have the biggest impact in the next few years?

Decorators are another big one, especially for those of us using TypeScript. Also, proxy-based observables seem like a lightweight alternative to state management libraries, which is awesome.
