Delete Documents in MongoDB Collections using deleteOne and deleteMany

In this lesson, we learn that deleting documents from MongoDB collections is straightforward with the deleteOne and deleteMany methods.

We demonstrate how to use deleteOne to remove a specific document based on its salary, confirming the deletion by querying the collection afterward.

We also explore the use of deleteMany to remove multiple documents that meet specified criteria, such as salaries greater than a certain amount.

Finally, we illustrate how to clear an entire collection by executing deleteMany with an empty query, resulting in the removal of all documents within the collection.
