Question

Where statements in Mongoose: Author.where(x).gte(25).lte(35).limit(10).sort('age').exec(function (err, docs) { console.log(docs); });

Option 1:
The code fetches documents with ages between 25 and 35, limits the result to 10, and sorts by age.

Option 2:
The code fetches documents with ages greater than or equal to 25 and less than or equal to 35.

Option 3:
The code fetches documents and logs the age property of each document.

Option 4:
The code has a syntax error.

Answer 1

The Mongoose query uses gte(25) and lte(35) conditions to fetch documents with ages within the specified range of 25 to 35. The other options either misinterpret the query or describe unrelated actions.Therefore, the correct option is Option 2: The code fetches documents with ages greater than or equal to 25 and less than or equal to 35.

Step-by-step explanation:

The Mongoose query provided uses the `where` method to filter documents based on the 'age' field. The `gte(25)` and `lte(35)` conditions specify that the age should be greater than or equal to 25 and less than or equal to 35.

This ensures that the code fetches documents with ages within the specified range. The `limit(10)` method restricts the result to a maximum of 10 documents, and `sort('age')` arranges the fetched documents in ascending order based on the 'age' property.

Breaking it down:

- `gte(25)`: Greater than or equal to 25.

- `lte(35)`: Less than or equal to 35.

- `limit(10)`: Limit the result to 10 documents.

- `sort('age')`: Sort the documents based on the 'age' field.

Therefore, the code is effectively fetching documents with ages between 25 and 35, limiting the result to 10 documents, and sorting them by age. Option 2 accurately describes the functionality of the provided Mongoose query.

Therefore, the correct option is Option 2: The code fetches documents with ages greater than or equal to 25 and less than or equal to 35.
