Methodically assess code to identify potential bugs, increase code quality, minimize code redundancy, optimize slow functions, and improve documentation.

Steps for code review:

1. Review the design: determine whether the suggested solution is consistent with the rest of application design and architecture.
2. Check correctness: ensure the code functions as expected and achieves the intended goal. This includes adding automated tests and/or manually testing code.
3. Review code style and standards: The code should follow style and standards of the team. Code style consistency makes the code easier to read and understand. This will also help future developers.
4. Check for code smells: Smells can indicate more serious issues in the code. Large classes or methods, redundant code, excessive complexity are examples.
5. Examine readability: Code should be easy to read and understand. Good code should be self-explanatory and have sufficient annotation.
6. Evaluate performance: Assess performance issues using profile/benchmarks. Identify processing bottlenecks and improve code efficiency.
