💡 Hint

Common Mistakes

Using limit instead of skip, which restricts the number of documents returned but does not skip.

Using sort or count which do not skip documents.

The skip method is used to skip a number of documents in the result set. Here, skip(5) skips the first 5 documents.

2fill in blank

💡 Hint

Common Mistakes

Using skip again instead of limit, which would skip more documents instead of limiting.

Using count which returns a number, not documents.

After skipping 10 documents, limit(5) restricts the output to 5 documents.

3fill in blank

Fix the error in the code to skip 3 documents correctly.

MongoDB

db.collection.find().[1](3)

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

💡 Hint

Common Mistakes

Writing skip3 without parentheses causes a syntax error.

Using skip. or skip[] are invalid syntax.

The skip method requires parentheses with the number inside: skip(3).

4fill in blank

hard

Fill both blanks to skip 7 documents and sort by 'age' ascending.

MongoDB

db.collection.find().[1](7).[2]({ age: 1 })

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

Blimit

Csort

Dcount

Attempts:

💡 Hint

Common Mistakes

Using limit instead of skip for the first blank.

Using count instead of sort for the second blank.

First, skip(7) skips 7 documents. Then, sort({ age: 1 }) sorts the remaining documents by age in ascending order.

5fill in blank

hard

Fill all three blanks to skip 4 documents, limit to 3 documents, and sort by 'name' descending.

MongoDB

db.collection.find().[1](4).[2](3).[3]({ name: -1 })

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

💡 Hint

Common Mistakes

Mixing up the order of methods.

Using count instead of sort for sorting.

The methods are chained: skip(4) skips 4 documents, limit(3) limits the result to 3 documents, and sort({ name: -1 }) sorts by name descending.
