• Primitive Obsession | Code Walks 055 - Christopher Okhravi - Using int to represent age vs Age for living people: the set of valid integers is greater than the set of valid ages – not all valid integers are valid ages / all valid ages are valid integers.

  • Are all values for this object (int, string, etc.), valid values for this domain concept (name, age, etc.)?
