Hướng dẫn what does find return in mongodb? - tìm thấy gì trong mongodb?

Tôi đang cố gắng đọc đầu ra của chức năng tìm từ kết nối MongoDB.

Tôi muốn lưu trữ kết quả của cơ sở dữ liệu cho JSON/mảng có tên là kết quả như:

collection= db.collection('users');
result =collection.find().

Ngay bây giờ với mã này kết quả là tôi đang nhận được một số đầu ra JSON dài kỳ lạ:
