Refactoring: Refactoring is the process of restructuring existing code without changing its external behavior. It aims to improve readability, performance, or maintainability while keeping the same functionality intact.
Version Control: Version control systems like Git help manage changes made to a project's source code over time. They enable collaboration among developers by tracking modifications and allowing easy rollback if needed.
Debugging: Debugging is the process of finding and fixing errors or bugs in a program's logic. It involves analyzing code execution and using tools like breakpoints or logging statements to identify issues.
