🔥 Welcome to Part 10 of the MongoDB Fundamentals, Functions & ORM Detailed Guide! In this episode, we explore how to use the powerful updateMany() method in MongoDB to modify multiple documents at once. This is essential when you need to apply bulk changes—like adjusting prices, toggling flags, or updating statuses—across a large dataset efficiently.

You’ll learn how to write safe, performant bulk updates using MongoDB Compass, the Mongo Shell, and Node.js with the MongoDB Driver.

✅ What You’ll Learn in This Video:

✔️ How to use updateMany() to target multiple documents
✔️ Writing effective filter queries to match bulk update conditions
✔️ Applying update operators like $set, $inc, and $unset
✔️ Executing updates in Compass GUI, Shell, and Node.js code
✔️ Verifying your changes with matchedCount and modifiedCount

💡 Why This Step Matters:

🔹 Empowers you to scale updates efficiently across large datasets
🔹 Helps maintain data integrity and consistency in bulk operations
🔹 Critical for real-world admin tasks like batch flagging or promotions
