Duplication

PreviousPerformanceNextCode Smell

Last updated 8 months ago

In code reviews, duplication issues refer to instances where the same or similar code appears in multiple places within a software project.

These redundancies can lead to several problems, including increased maintenance overhead, difficulty in debugging, and potential inconsistencies in functionality. Duplicate code can arise due to copy-pasting sections of code without proper abstraction or reuse, resulting in bloated and harder-to-manage codebases. Additionally, duplicated logic increases the likelihood of introducing bugs or inconsistencies when one instance of the code is updated but not others.

By identifying and addressing duplication issues during code review, developers can improve code maintainability, reduce the risk of errors, and enhance overall code quality. Strategies such as refactoring common code into reusable functions or using inheritance and polymorphism can help mitigate duplication and promote cleaner, more maintainable code.
