mongoose find statement

Hello all, i am trying to get all the faculties in the university schema below:

let universitySchema = new Schema({ name: String, description: String, faculties: [facultySchema], universityBuildings: [universityBuildingsSchema], students: [userSchema], banks: [bankSchema], atms: [atmSchema], foods: [foodSchema], icon: String });

let University = Mongoose.model('University', universitySchema);

using the University Object, how would i get the results of all the faculties only?

What i currently have:

// Get /faculties // Route to get all faculties router.get('/university/:uID/faculties', (req, res, next) => { // Return all faculties University.find({}, null, (error, faculty) => { if(error) return next(error); res.json(faculty); }) });

The above code returns the university document i know, just need help getting only faculties.

Thanks in advance guys.

Thank you Lucas however that doesn't seem to work for me. Maybe i am doing something wrong, i am trying to create a REST API where persons request the faculties and the faculties is sent back to the client. How would i convert the code below to achieve that. when i add the select method i get an error stating select statements accept only one argument. however i want to use a callback function to handle the response.

router.get('/university/:uID/faculties', (req, res, next) => {
   // Return all faculties
   University.find({}, null, (error, faculty) => {
       if(error) return next(error);
       res.json(faculty);
   });
});
