Possible to populate two levels?

Question

Say I have collections/documents like below:

question collection:

{
   _id: ObjectId(\"0000\"),
   title: \"test question\",
   survey: ObjectId(\"1234\"         


        

Answer 1

I guess the best is to nest in the top populate and make it as a object

 Court.
  findOne({ name: 'Val' }).
  populate({
    path: 'events',
    populate: { path: 'authorId' }
  });
