Frequently Asked Questions
Why does each && add complexity?
Because short-circuit logical operators introduce a hidden branch: the right side runs only if the left side resolves a particular way. Each is an independent path.
Should I always refactor at CC > 10?
Use it as a signal, not a rule. A switch over 20 enum cases may have CC of 21 but be very simple to read. CC catches dense conditional logic best.
What is cognitive complexity?
A metric by SonarSource that adds extra weight to nested constructs, recursion, and break/continue. It correlates better with how hard code is to understand.
