Note: Just take a quick overview of this for now — we will learn it thoroughly throughout the notes.

🧩 What is Mongoose?

Mongoose is an ODM (Object Data Modeling) library for MongoDB and Node.js.

It helps developers interact with MongoDB by using JavaScript objects and adding structure to data.

🧠 In Simple Terms

Without Mongoose:

• MongoDB stores documents without strict rules (schema-less)

With Mongoose:

• You define schemas (structure and rules)
• You create models to interact with the database
• You get validation, defaults, and query helpers

🔧 What Mongoose Does

• Defines schemas (data structure)
• Creates models (for interacting with collections)
• Adds validation
• Simplifies CRUD operations (Create, Read, Update, Delete)
• Enables middleware (hooks like pre-save, post-remove)
