Legacy Code Refactoring

Legacy code refactoring is the process of improving the structure and design of existing code without changing its functionality. This is a common task in software development, as codebases often become cluttered and difficult to maintain over time. Legacy code refactoring can help to improve the readability, maintainability, and performance of code, making it easier to work with and less prone to errors.

Why Refactor Legacy Code?

There are many reasons why you might want to refactor legacy code. Some of the most common reasons include:
