Cursor Methods - MongoDB Manual v8.0
The methods listed on this table of contents page are mongosh methods. This is not the documentation for Node.js or other programming language specific driver methods. In most cases, mongosh methods work the same way as the legacy mongo shell methods. However, some legacy methods are unavailable in mongosh. For Mongo DB API drivers, refer to the language specific Mongo DB driver documentation.
