What are the best practices for refactoring code?
Refactoring code involves improving its structure without changing its behavior. Key practices include: 1. Write tests before refactoring. 2. Refactor in small steps. 3. Keep functions small and focused. 4. Use meaningful names for variables and functions. 5. Avoid duplication.
Can you explain why writing tests first is important?
Writing tests first ensures that you have a safety net to catch any unintended changes in behavior during refactoring. It helps maintain code integrity.
What tools can assist in the refactoring process?
Some popular tools for refactoring include IDEs like IntelliJ IDEA and Visual Studio, as well as static analysis tools like SonarQube and ESLint.
How often should I refactor my code?
You should refactor your code regularly, ideally after completing a feature or fixing a bug, to keep the codebase clean and maintainable.
