if u have been through the node course and in the CRUD operations using mongoose section in the first lecture mosh told “u will not become a mongo db expert by the end of the course but u will get the job done”
now please don’t think he is not teaching complete mongo db
here he is not teaching the features of the mongo db raw driver but he teaching mongoose which very good because mongo db driver is outdated and is of no use but ya some features r good of the raw mongo db driver which is covered in the course because as u know if u have wen through the lectures that the driver is built up on the raw mongo db driver!.
conclusion === Mongoose is built up on raw mongo db driver so no need to think about it
just go with mongoose with no worries just like how mosh is gonna/ teached u in his lectures
