CodeSphere ⚛️ Ep.2 – React Reconciliation Explained

🚀 CodeSphere ⚛️ Ep.2 – React Reconciliation Explained | How React Decides What to Update

In the previous episode, we learned about the Virtual DOM. But what happens after React creates a new Virtual DOM tree?

How does React compare the old and new trees?
How does React know exactly what changed?
Why are React updates so efficient?

In this episode, we'll dive deep into **React Reconciliation** — the process React uses to compare Virtual DOM trees and update only the necessary parts of the UI.

📚 What You'll Learn:

✅ What Reconciliation is
✅ How React compares Virtual DOM trees
✅ React's Diffing Algorithm Explained
✅ Why React doesn't rebuild the entire UI
✅ Component Reconciliation
✅ Child Reconciliation
✅ The Importance of Keys in Lists
✅ State Preservation During Updates
✅ Reconciliation vs Diffing
✅ Common React Interview Questions

By the end of this video, you'll understand the engine behind React updates and why React applications remain fast even as they grow in complexity.

🔥 In the next episode, we'll explore **React Fiber Architecture** and learn how React schedules, prioritizes, and manages rendering work behind the scenes.
