First of all, I don't recommend depending on the client to give you the actual quantity (See
updatedProduct.quantity - 1) cause you can never trust it. I would fetch it first and see there is a product with that id and get the quantity from there, or even set the quantity using the$inc operatorhttps://www.mongodb.com/docs/manual/reference/operator/update/inc/
I didn't understand questions number 2 and 3. Can you explain further?
