Simple Design: No* Duplication

This article, part of a series on the Four Rules of Simple Design, focuses on the principle of 'No Duplication.' It explains that duplicating domain logic (like checking if a user account is active) across code makes software harder to understand, test, and change. The post argues that consolidating such logic into a single function improves abstraction, prevents errors, and, most importantly, supports future modifications.
