The Full Stack Web Development - Cursor Methods

The video tutorial covers the use of MongoDB cursor methods, focusing on sorting, limiting, and skipping documents in queries. It explains how to assign cursors to variables, iterate through them using next and hasNext methods, and loop through results with forEach. The tutorial provides practical examples and code snippets to demonstrate these concepts effectively.
