Скачать или смотреть #62 Event Delegation | JavaScript Interview Question |

In this video, we’ll learn one of the most powerful and misunderstood concepts in JavaScript — Event Delegation.
Most beginners add individual event listeners to each element like li, but as soon as new elements are added dynamically… the click stops working.
Why? Because the event listener was never attached to the new element.

In this short demo, I’ll walk you through:

✅ The beginner approach (adding event listeners to each element)
❌ Why it fails when elements are added dynamically
⚡ How Event Delegation solves this problem
🧠 How event bubbling allows one parent listener to handle all child clicks
🚀 A clean, scalable, and professional way to handle events in real projects

By the end, you’ll clearly understand when and why to use Event Delegation—and you’ll never attach multiple event listeners unnecessarily again.
