MongoDB CRUD Operations: Replace Documents
Quick Answer
In MongoDB, replacing a document means completely overwriting an existing document with a new one using the replaceOne() method. This operation requires specifying a filter to match the document and providing the replacement document. It is useful when you want to update an entire document rather than modifying specific fields.
