Code refactoring refers to the process of improving the structural design, readability, and maintainability of existing code without changing its external behavior. It involves making changes to the code to simplify it, remove duplication, improve performance, or adapt it to follow best practices.
Example: If a software developer identifies a complex and convoluted portion of code in an application, they may refactor it by breaking it into smaller functions or classes, improving naming conventions, or optimizing performance to make it more readable and maintainable.
