Code Refactoring

Code refactoring is the process of restructuring existing computer code without changing its external behavior. It involves cleaning up, reorganizing, or improving the code's internal structure to make it more efficient, readable, and maintainable. This helps developers quickly understand and modify the code in the future, reduces the chance of bugs, and enhances overall performance. Think of it like renovating a building: you improve the layout and design inside without altering its basic function or appearance from the outside.
