MongoDB Basics

Documents, queries, and the joy of schemaless (until you need a schema).

Learn MongoDB from the shell: insert, find, filter, update, delete, and basic aggregation. Real documents, real queries — no ORM hand-waving.

Learn with Ada, your AI coding mentor — ask questions or tap I’m stuck in any lesson for a nudge without spoilers.
