9 Common Code Quality Issues and Solutions
The article outlines nine frequent code‑quality problems—such as inconsistent naming, overly long functions, missing or outdated comments, poor error handling, lack of reuse or modularity, hard‑coded values, insufficient testing, misguided performance tweaks, security oversights, and weak version‑control practices—and offers practical solutions to address each.
