Thanks for the help on the projection

[Ohshi60]

Hi, i just wanted to say your code saved me from a nightmare, and i was hoping you could help me explain a bit. The issue is with the lesson 4 project find:
The official docs state that i can use collection.find with a query and a projection
https://docs.mongodb.com/manual/reference/method/db.collection.find/#explicitly-exclude-the-id-field
collection.find({ age: { $gt: +age } }, { _id: 0 })
but the code doesnt apply the projection unless i do it like in your solution wrapping the projection in fields:
.find({ age: { $gt: +age } }, { fields: { _id: 0 } })

So i guess my question is? How did you know to apply the fields: in the projection, i cant find it in the official docs

Again thank you very much i was stuck on this problem for so long, just hoping for a bit of clarification
