How do you prepare for a code review session?

1 Choose the right reviewer

The first step is to select a reviewer who has the relevant expertise, availability, and interest to review your code. You want someone who can provide constructive feedback, spot errors, and suggest improvements. You also want someone who is familiar with the project, the coding standards, and the tools you use. Ideally, you should have a regular reviewer who knows your work and can track your progress.

2 Write clear and concise code

The second step is to write code that is easy to read, understand, and test. You should follow the coding style and conventions of your team or project, and use consistent naming, formatting, and indentation. You should also document your code with comments, docstrings, and annotations that explain the purpose, logic, and assumptions of your code. You should avoid unnecessary complexity, duplication, and ambiguity, and refactor your code to make it more modular and reusable.

4 Write a descriptive commit message

The fourth step is to write a descriptive commit message that summarizes the changes you made and the reasons behind them. You should use a standard format and language that your team or project agrees on, and include relevant information such as the issue number, the feature name, and the reviewer's name. You should also highlight any important or controversial aspects of your code, such as new dependencies, design decisions, or trade-offs. You should avoid vague or generic messages that do not provide enough context or detail.

6 Respond to feedback promptly and politely

The sixth and final step is to respond to feedback promptly and politely. You should review the comments and suggestions that the reviewer provides, and acknowledge them with gratitude and respect. You should also address any issues or questions that the reviewer raises, and explain your reasoning or rationale for your code. You should also implement any changes or improvements that the reviewer recommends, and update your code and your pull request accordingly. You should also communicate any challenges or difficulties that you encounter, and ask for help or clarification if needed.
