Scenarios-based learning is awesome...Easy to grasp

[@bytequest1552]

Your intutive and application based way of teaching inspires me, great series. Just one question that I have, I feel strong connections between sql queries and aggregation pipelines, I see that they do similar work but, for different types of DBMS

[@ridamsinghal1073]

Sir, this video really helps me to make my hold on MongoDB aggregation pipeline stronger. It also helps me in your video on Learn MongoDB aggregation on chai aur code. Thank you sir for this.

[ { $project: { numberOfTags: { $size: "$tags" } // Add a field to each document representing the number of tags } }, { $group: { _id: null, averageTagsPerUser: { $avg: "$numberOfTags" } // Calculate the average number of tags } }, { $project: { _id:0, averageTagsPerUser:1 } } ] Another Way!

[@ijasbasheer7263]

thanks sir

[@Lguabed]

Thanks you for this video. I think only it is better to use $size of array tags instead of $unwind like that { $group: { _id: null, avgtags: { $avg: { $size : "$tags"}, }, }, } it give the same result

Hi Sir, Thanks for series Love it ❤❤ I have gone through the docs and I found the another possible solution for this question please check if it's correct [ { $group: { _id: null, tagAvg: { $avg: { $size: { $ifNull: ["$tags", []] } } } } } ]
