What are the best practices for refactoring legacy code?
Refactoring legacy code involves several best practices, such as understanding the existing code, writing tests, and making small incremental changes.
Why is it important to write tests before refactoring?
Writing tests before refactoring ensures that you have a safety net to catch any bugs introduced during the refactoring process.
Can you give me an example of a small incremental change?
Sure! A small incremental change could be renaming a variable to make its purpose clearer, which can improve code readability.
How do I prioritize which parts of the code to refactor first?
Prioritize areas of the code that are most frequently modified, have the highest complexity, or are critical to the application's functionality.
