MongoDB Delete
Delete Documents
We can delete documents by using the methods deleteOne() or deleteMany().
These methods accept a query object. The matching documents will be deleted.
deleteOne()
The deleteOne() method will delete the first document that matches the query provided.
Example
db.posts.deleteOne({ title: "Post Title 5" })
deleteMany()
The deleteMany() method will delete all documents that match the query provided.
Example
db.posts.deleteMany({ category: "Technology" })
