  27. insertMany

    The insertMany() method in MongoDB is used to insert multiple new documents into a MongoDB database.

  28. insertOne

    The insertOne() method in MongoDB is used to insert a single new document into a database.

  29. Introduction to MongoDB collection.insert() Method

    The insert() method in MongoDB is used to insert a new document into a MongoDB database.

  30. Introduction to MongoDB collection.update() Method

    In MongoDB, the update() method is used to modify data in one or more documents.

  31. isCapped
