I want this to work. But it doesn't.
let today = new Date()
book.dueDate = today.setDate(today.getDate() + 14);

returns a number and not an object.
But you could do something like this instead:
book.dueDate = new Date();
book.dueDate.setDate((new Date()).getDate() + 14);
And you can skip the first line if book.dueDate
is already a Date
object.
