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. Using Age allows for validation, formatting, comparisons, and makes dependencies explicit.
- Are all values for this object (int, string, etc.), valid values for this domain concept (name, age, etc.)?
