[journal] Friendly Little Wrapper Types

Read Original

This article, aimed at software developers, debates the utility of creating wrapper types for simple identifiers (like UserId) versus using primitives. It argues that such types reduce errors and add semantic clarity, even in services where the identifier is not a core concern, contrasting with the view that they add unnecessary complexity.
