What do you pay attention to during a code review?

During code review, I pay attention to several key aspects:

• Readability and maintainability of the code: ensuring the code is understandable by other developers, using clear variable and function names, and avoiding unnecessary complexity.
• Compliance with architectural and style standards: verifying that the code adheres to the patterns and guidelines adopted in the project.
• Logic and correctness of implementation: ensuring that algorithms work correctly and cover all necessary cases.
• Error and exception handling: checking that errors are handled properly and do not lead to crashes.
• Tests: presence and quality of unit and integration tests, covering important scenarios.
• Performance and optimization: assessing whether there are bottlenecks or redundant operations.

For example, if I see a long method, I suggest breaking it into smaller parts to improve readability and reusability.
