What is Clean Code?
Turkish: Clean Code
Clean Code is a way of writing software that makes intent clear, keeps units small, and reduces the cost of future change.
What is Clean Code?
Clean Code is a way of writing software so that its intent is clear to the next person reading it. The goal is not decoration; it is reducing the mental load and risk involved in changing the code later.
Clean code uses names that explain intent, keeps functions small and close to one responsibility, removes duplicated logic, and makes side effects visible. Error messages, edge cases, and tests are also part of readability because they explain expected behavior.
Practical Principles
Clean Code does not mean making every line short. Sometimes an explicit condition is easier to understand than an over-abstracted helper. The important question is whether the team can change the code safely.
Good tests support clean code by making behavior explicit and reducing refactoring risk. Code review, lint rules, and shared naming conventions help keep the approach consistent across a team.
SOLID principles are often discussed with Clean Code, but they should not be applied mechanically. As technical debt grows, readability drops; steady small improvements are usually healthier than rare, risky rewrites.
