Delete Your Code!

Deleting code is a critical developer skill that serves two purposes: understanding complex systems and improving code quality. When inheriting legacy codebases, strategic deletion reveals dependencies and clarifies architecture. The practice involves removing dead code, duplicate logic, and unused features while using techniques like Git bisect and feature flags. Effective deletion requires discipline through small reversible changes, test coverage, and peer review. Developer value comes from managing complexity, not maximizing lines of code written.
