Mongoose Population

Mongoose Population is a feature in Mongoose, a popular library for working with MongoDB in Node.js. It allows you to easily retrieve related data from different collections in your database. For example, if you have a collection of users and a collection of posts, population lets you fetch posts with the corresponding user details all in one query. This is useful for reducing the number of database calls and simplifying data management, as it helps bring related information together seamlessly, making it easier to work with complex data relationships.
