Great article on modern JavaScript! I've been using the new optional chaining and nullish coalescing operators, and they've been game-changers for cleaner code. Would love to see a deep dive into the performance implications of some of these newer features.
Thanks for the suggestion, Sarah! I'm actually working on a performance-focused follow-up article that will cover exactly that. Stay tuned!
