What do you pay attention to during a code review of someone else's code?

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

• Readability and clarity of the code. The code should be easy to understand, without unnecessary complexity.
• Compliance with the project's style and standards. It is important that the code is consistent with the rest of the codebase.
• Logic and correctness of implementation. I check that the code does what it claims and that there are no logical errors.
• Error and exception handling. Ensure that errors are handled correctly and do not lead to crashes.
• Tests. The presence and quality of unit and integration tests.
• Performance and resource consumption. I evaluate whether there are bottlenecks or suboptimal solutions.
• Security. I check for vulnerabilities, such as SQL injections or data leaks.

This approach helps maintain the quality and reliability of the code in the project.
