MongoDB Course Beginner to Advanced (YOOBABA)

A focused MongoDB course in Hindi/Urdu from YOOBABA, 33 lessons and about 14 hours. After an introduction and installation on Windows and macOS, it creates databases and collections, inserts documents, explains data types and JSON schema validation, and covers updating, replacing, deleting and finding documents. It then works through comparison, logical, element and evaluation query operators and findOneAndUpdate/Replace/Delete. A long aggregation section explains pipeline stages such as $group, $lookup, $bucket, $addFields, $unwind, $out, $merge, $unionWith and $facet, plus arithmetic, string, date, array, type and conditional operators. It ends with capped collections, indexes, importing JSON, backup and restore, and user authentication. Good for MERN learners.
