Welcome to Part 20 of the Ultimate Guide to Server-Side Scripting series! In this session, we’ll complete the CRUD cycle by implementing Update (PUT/PATCH) and Delete (DELETE) routes in your Express.js + MongoDB backend. These routes allow you to modify and remove data efficiently while maintaining data integrity and security across your API endpoints.

✅ What You’ll Learn in This Video:
✔️ Creating Update routes to modify existing records in MongoDB
✔️ Handling DELETE requests to safely remove records
✔️ Using Mongoose methods like findByIdAndUpdate() and findByIdAndDelete()
✔️ Implementing error handling for invalid IDs and missing records
✔️ Structuring JSON responses for easy frontend integration

💡 Why This Step Matters:
🔹 Finalizes the full CRUD (Create, Read, Update, Delete) API setup
🔹 Enables seamless data management across your applications
🔹 Builds a strong foundation for admin dashboards and CMS systems
🔹 Helps you understand safe and efficient data mutation techniques
