What are some best practices for refactoring code?
Some best practices include keeping changes small, writing tests before refactoring, and ensuring code readability.
Why is it important to write tests before refactoring?
Writing tests before refactoring helps ensure that existing functionality is preserved and allows you to catch any errors introduced during the process.
Can you give an example of a small refactoring?
Sure! An example would be renaming a variable to make its purpose clearer, like changing 'x' to 'userCount'.
How often should I refactor my code?
It's good to refactor regularly, especially when you notice code smells or before adding new features.
