What do you pay attention to during code review?

When conducting a code review on the frontend, I pay attention to several key aspects:

• Readability and maintainability of the code: clear variable and function names, logical component structure.
• Compliance with style and project standards: consistent formatting, use of linters.
• Optimality and performance: avoiding unnecessary re-renders, optimizing DOM operations.
• Security: protection against XSS, proper handling of user input.
• Responsiveness and cross-browser compatibility: ensuring the UI displays correctly on various devices.
• Tests: presence of unit and integration tests covering key functionality.
• Architecture and patterns: proper separation of concerns, use of appropriate libraries and approaches.

For example, if I see a component with many props and complex logic, I might suggest breaking it into smaller parts to improve readability and reusability.
