💡 Hint

Common Mistakes

Using skip() instead of limit() will skip documents rather than limit the count.

Using sort() changes order but not the number of documents.

Using count() returns a number, not documents.

The limit() method restricts the number of documents returned by the query. Here, it limits the result to 5 documents.

Complete the code to skip the first 10 documents and then limit the result to 5 documents.

💡 Hint

Common Mistakes

Using sort() here will reorder documents but not limit the count.

Using count() returns a number, not documents.

Using aggregate() is for complex pipelines, not simple pagination.

After skipping the first 10 documents, limit(5) returns the next 5 documents for pagination.

3fill in blank

hard

Fix the error in the code to correctly paginate by skipping 20 documents and limiting to 10.

MongoDB

db.collection.find().skip(20).[1](10)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Placing limit() before skip() can cause unexpected results.

Using count() instead of limit() returns a number, not documents.

Using sort() does not limit the number of documents.

The limit() method should come after skip() to correctly paginate. The correct order is skip(20).limit(10).

Fill both blanks to skip the first 15 documents and limit the result to 7 documents.

MongoDB

db.collection.find().[1](15).[2](7)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Reversing the order of skip and limit.

Using sort() or count() instead of skip or limit.

Not using both methods together for pagination.

To paginate, first skip the documents you don't want, then limit how many you want to see.

5fill in blank

hard

Fill all three blanks to sort documents by 'date' descending, skip 30 documents, and limit to 10 documents.

MongoDB

db.collection.find().[1]({ date: -1 }).[2](30).[3](10)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using count() instead of limit() returns a number, not documents.

Changing the order of methods can cause wrong results.

Not sorting before skipping and limiting when order matters.

First, sort documents by date descending. Then skip 30 documents and limit the result to 10 for pagination.
