Software Refactoring
Software 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 making small, incremental changes to clean up code, reduce complexity, and eliminate technical debt while ensuring the software continues to function correctly. This practice is a core component of modern software development methodologies like Agile and DevOps.
Developers should learn and apply refactoring when code becomes difficult to understand, modify, or extend due to issues like duplication, poor design, or outdated patterns. It is essential during feature development, bug fixes, or code reviews to prevent technical debt from accumulating and to facilitate future changes. Specific use cases include preparing code for new features, improving testability, and optimizing performance without altering user-facing functionality.
