Advent of Pull Requests Best Practice - Day 19

In a previous post, I discussed leveraging tools like Sonarcloud to assess the complexity in pull requests. It's important to remember, though, that these tools don't replace the need for a manual review. Ultimately, you and your team are responsible for comprehending the code going forward.

Here are some tips for navigating complex code:

• Seeking Clarity and Enhancing Documentation: If you encounter code segments that are obscure or overly complicated, don't hesitate to ask the author for clarification. Encourage them to include additional comments or documentation to demystify complex logic or algorithms. This approach helps not only in your immediate review but also assists anyone who works with the code in the future.
• Advocating for Code Simplification: Whenever you spot opportunities, suggest ways to streamline the code. This could mean breaking down hefty functions into smaller units, unraveling intricate conditional logic, or applying design patterns for better clarity and maintainability.
• Assessing the Need for Complex Solutions: Sometimes, the nature of the problem demands complex solutions. In such cases, verify that the complexity is necessary and managed well. Complex operations, like sophisticated mathematical calculations or data processing, should ideally be contained within well-documented and separate modules or functions.

Complexity is sometimes unavoidable, but we can try to manage it.
