Learn how to control your MongoDB query results using skip() for pagination and Projection to select only the fields you need. This is essential for optimizing your queries and making your application faster.

What you will learn:

db.collection.skip(): How to skip a certain number of documents from the beginning of a query result. This is the foundation for building pagination (e.g., skipping the first 10 results to show "Page 2").

Projection (Selecting Fields): How to specify exactly which fields to return in your results, which saves bandwidth and processing time.

Include fields: db.users.find({}, { name: 1, email: 1 })

Exclude fields: db.users.find({}, { password: 0, address: 0 })

How to hide the _id field: db.users.find({}, { name: 1, _id: 0 })

Combining skip(), limit(), and sort(): We'll show you how to put it all together to create a powerful and efficient query for pagination (e.g., db.posts.find().sort({ date: -1 }).skip(20).limit(10)).
