Code refactoring, the process of restructuring existing code while preserving its external behavior, is a crucial activity in software development. However, there are different ways to describe this process. Some synonyms for code refactoring include code restructuring, code optimization, code cleanup, code renovation, and code reorganization. These terms all describe the essential act of improving code quality and maintainability by altering its internal structure. Code refactoring can help eliminate redundancies, improve readability, and enhance performance. Whatever term is used, the goal is the same: to create a more appropriate design for the coding structure that better fulfills its intended functionality while making future modifications easier.
