Question About MongoDB findOne Alternative

[Rohith]

How can we fetch a single document from a MongoDB database? Since the findOne operation is not available in the options, is there an alternative operation that can achieve the same result?

I tried using the find operation with a query, and when I logged the result, it appeared twice, first with the entire collection and then with only the expected document.

You can achieve the same result using the find operation with a limit. Since find returns a cursor that can retrieve multiple documents, you need to apply { "limit": 1 } to ensure only a single document is returned.

You can add the limit in the Options section
