When encountering commented-out code during refactoring, what should you do?

During the refactoring process, maintaining clean and maintainable code is essential. Deleting commented-out code when it is no longer needed contributes to better readability and clarity. Commented-out code can create confusion for developers, as it may lead to uncertainty about whether the code serves a purpose or should be considered a potential solution in the future. By removing it, you create a more streamlined codebase, making it easier for current and future developers to understand the logic and purpose of the surrounding code. This approach aligns with best practices in software development, which advocate for simplicity and clarity, ultimately improving overall code quality and maintainability.
