When code becomes complicated during development, how do you handle it?

Question

During development, complex logic inevitably emerges. While I try to keep things as simple as possible, there are times when no matter what I try, I can't make the code simple. It makes me uncomfortable whenever I encounter these situations.

How do you all handle development in these situations? I suppose things like adding comments would be one approach.

If the problem is complex, some complexity in the code is fine. Just make sure it’s understandable! 😄

I think it’s difficult to completely eliminate complex logic. I also try to simplify my code as much as possible, but realistically there are times when that’s just not feasible. In those cases, I break the logic down into smaller units and clearly define the role of each one. If there are inevitably complex parts, I supplement them with appropriate comments and documentation so that others (or even my future self) can easily understand them later. Sometimes it’s also a good idea to hide or abstract the complexity, so I keep the possibility of refactoring open to polish the structure further down the line.

I do add comments, but first, as the logic becomes more complex, I look for alternative approaches. I try to find ways to separate the logic and keep it as concise as possible.
