What is business logic in relation to layout of menu items?
(and in general what does this fashionable term mean)

Answer 1

Why is he trendy?
This is just a term that refers not to technical logic, but to business logic.
It is logical that in the online store the menu should be "read" - "add to cart" - "checkout" - "confirm", and not
"confirm" - "add to cart". And this is business logic, because technically it can be implemented in any way without violating the syntax of the programming language.
Business logic should also include marketing and interface friendliness.
