Code Refactoring
Code refactoring is the process of restructuring existing computer code without changing its external behavior to improve non-functional attributes such as readability, maintainability, and performance. It involves techniques like renaming variables, extracting methods, and simplifying complex logic to make the code cleaner and easier to understand. This practice is essential in software development to reduce technical debt and adapt code to evolving requirements.
Developers should learn and apply code refactoring to enhance code quality, reduce bugs, and facilitate future modifications, especially in long-term projects or when inheriting legacy code. It is crucial during code reviews, before adding new features, or when performance issues arise, as it helps maintain a sustainable codebase and improves team collaboration by making the code more transparent.
