What will be the result of using curser.limit(3) in a query?

Using cursor.limit(3) in a MongoDB query means that the query will restrict the number of documents returned to a maximum of 3. This is commonly used to manage the volume of data fetched from the database, especially when dealing with large datasets. By applying this limit, you ensure that only the first 3 documents that match the query criteria will be retrieved and sent back as the result set.

It's important to note that the documents returned are based on the natural order of the database or any specific sorting applied before the limit is enforced. If no sorting criteria are specified, it effectively returns the top 3 documents as they appear in the underlying storage of the database. This behavior is particularly useful in applications that need pagination or simply want to display a limited number of results to users at a time.
