[Sophie]

Thanks for your prompt reply Edin! I appreciate that.

One more thing, Edin, would you pls fix this part of code, otherwise someone will run into a ReferenceError: next is not defined :-) Thanks again!

book.save((next, err) => {
        if (err) {
            return next(err);
        }
        res.send('Book created successfully!');
    });
