Manual Code Refactoring
Manual code refactoring is the process of restructuring existing computer code without changing its external behavior to improve its internal structure, readability, maintainability, and performance. It involves making small, incremental changes to clean up code, remove duplication, and enhance design patterns, typically done by developers through direct editing of source files. This contrasts with automated refactoring tools, relying on human judgment to apply techniques like extracting methods, renaming variables, or simplifying conditional logic.
Developers should use manual code refactoring when working on legacy systems, during code reviews, or as part of regular maintenance to reduce technical debt and prevent bugs. It is essential in scenarios where automated tools cannot handle complex logic changes, such as improving algorithm efficiency or adapting code to new design patterns, and it helps teams maintain high code quality standards in long-term projects.
