MongoDB .populate

I'm currently learning MongoDB why do we use .populate(). What is the difference between .populate() and .virtual()?

Can anyone tell me how they differ and when one should be used over the other?

Both serves a different purpose and one cannot be a replacement of other.

Virtual: If you want attributes that you can get and set but that are not themselves persisted to mongodb, virtual attributes is the Mongoose feature for you.Remember, only non-virtual properties work as part of queries and for field selection.See Virtual

Populate: ObjectIds can refer to another document in a collection within our database and be populate()d when querying.It gives you DBRef-like behavior. See Populate
