JavaScript Iterators vs. Arrays: Who Wins in Performance? (10M Speed Test!) ⚡

Описание: 🚀 In this video, we test JavaScript Arrays vs. Iterators with 10 MILLION size to see which one is faster!

🔍 Key Takeaways
✅ Arrays use eager evaluation (processes ALL elements, even if you only need a few).
✅ Iterators use lazy evaluation (only computes what’s needed, stopping early).
🔥 Result? iterators can be 100x faster when you only need a subset of data!
