MongoDB Aggregation Lookup – Left Outer Join || MERN Tutorial

Yo! Whatzuuup you guys! In this tutorial we are going to understand how to use MongoDB aggregation pipeline stages, particularly the $lookup which is equivalent to the SQL left outer join. The part with actual aggregation is finished in the first 13 minutes or so, the rest of the tutorial is dedicated to outputting the aggregation results to the React bootstrap tables for better visualization and understanding. Hope you’ll stay through the video 🙂 Have a nice safe day!
