It would be very kind of you to solve this for me how can i get all the users whose users ids present in users friendlist array For reference u can see this stackoverflow.com/questions/66497145/how-can-i-ge…

Honey I'm still learning this like you, but I'll give it a shot 🤟

Since you have the array of friend IDs, I'd try the $or operator:

const list = YourModel.find({ $or: [ { friendId_1 }, { friendId_2 }, ... ] })

Hope that works... (you're using mongoose, right?)

I got the solution I use aggregate function jsdisco

Good to know, I have yet to explore how to write more advanced queries. That'll definitely be one of the next articles.
