↩️ How does Ctrl + Z (Undo) work even after multiple changes?

Ever wondered how editors remember every action you performed? 😳

In this video, we explain the system design behind the Undo feature.

📌 Topics covered:
📚 Command Pattern
📦 Stack Data Structure (LIFO)
🔁 Undo & Redo operations
📜 Event Sourcing
⚡ Snapshots for performance optimization

How it works:

1. Every user action is stored as a command
2. Commands are pushed into a stack
3. Undo reverses the latest action first
4. Redo restores undone actions

This allows editors to rollback changes step by step efficiently.

📌 Real-world concepts:

* Data Structures
* System Design
* History Tracking
* Reversible Operations
