Daily Term: Refactoring

Refactoring

Refactoring is the process of restructuring existing code to improve its readability, maintainability, or performance without altering its external behavior. For example, a developer might extract a repeated code block into a function to reduce duplication. Refactoring keeps code clean and adaptable, often supported by automated tests to ensure functionality remains intact, but it requires discipline to avoid introducing bugs during changes.
