Primitive Obsession Primitive Obsession describes code in which the design relies too heavily on primitive types, rather than solution-specific abstractions. It often results in more verbose code with more duplication of logic, since logic cannot be embedded with the primitive types used. Sponsor - DevIQ Thanks to DevIQ for sponsoring this episode!

Show Notes / Transcript Primitives refer to built-in types, like bool, int, string, etc. The primitive obsession code smell refers to overuse of primitive types to represent concepts that aren't a perfect fit, because the primitive supports values that don't make sense for the element they're representing.

Many systems will use an int to represent a value that cannot be negative, such as the number of items in a shopping basket. In such a case, if the system even bothers to enforce the invariant statin
