We cover why primitive obsession is a problem, and how to solve it in both dynamic and typed languages. Seeing the same technique implemented in various languages helps give you context, see the tradeoffs more clearly, and see how it is a core problem regardless of language and tool set. It'll help make your code more likely to work and more readable for you and your co-workers.
