Описание: 📜 Description:
Welcome to today’s session on Event Delegation in ReactJS — a smart technique that helps improve your app’s performance, clean up code, and make event handling more efficient.

In this video, you’ll learn:
✅ What Event Delegation means in React
✅ Why React uses Synthetic Events
✅ Real-life example: “The Tech Fest Chief Guest Story”
✅ Practical implementation with a simple button click example
✅ Advantages of Event Delegation
✅ When and how to use it effectively

🧠 What is Event Delegation?
Event Delegation is a technique where one event listener on a parent element handles events from its child elements. Instead of adding event listeners to each child, React listens at the root and delegates events internally, making the app more efficient.

💻 Code Example Covered:

Attaching a single onClick listener to a parent div

Detecting which child button was clicked

Understanding event bubbling in React’s synthetic event system

📌 Why it matters:

Reduces memory usage

Boosts performance for large UIs

Keeps your code cleaner and more maintainable
