Top 10 Clean Code Rules
According to Uncle Bob’s “Clean Code” book, he defines guidelines and rules that developers should adhere to, particularly crucial for those with less experience. As developers gain more expertise, there is room to adapt or innovate these rules with justification.
Key principles from the book include:
- No Code Comments: Ideally, code should be self-explanatory without the need for comments. Variables, methods, and other components should have clear and descriptive names.
- Delete Dead Code and Comments: Unused code or comments should be promptly removed, often identified through version control systems.
- Boundary Testing: Boundaries in code should always be unit tested to avoid assumptions about behavior.
- Positive Conditionals: Positive conditionals are generally easier to understand than negative ones.
- Adhere to Standards: Follow standard architecture, coding practices, and design guidelines rigorously, utilizing tools to ensure compliance.
- Clear and Consistent Naming: Use names for variables, methods, and classes that are understandable from the perspective of the caller, maintaining consistency throughout.
- Apply the KISS Principle: Avoid unnecessary complexity; simplicity in design and code should be prioritized to prevent redundancy.
- Use Exceptions: Instead of return codes, exceptions should be thrown in exceptional cases where a method fails to fulfill its intended purpose.
- Keep Methods Small: Aim for concise methods, ideally fewer than 100 lines of code to enhance readability and maintainability.
- Boy Scout Rule: Continuously improve code by leaving it cleaner than when you found it, without requiring explicit permission to refactor.
