Ensure clarity, maintainability, and proper handling of all cases.
In large-scale applications, switch expressions should be designed to maintain clarity and avoid complexity. This involves ensuring all possible cases are covered, including a default case, and maintaining consistent return types across all branches. When dealing with complex business logic, such as processing different types of transactions, switch expressions can help streamline decision-making processes while minimizing errors.
