Avoid Null Returns
Instead of returning null, consider: throwing an exception for unexpected missing data, returning an empty collection for list operations, using the Null Object pattern, or using Optional/Maybe types. When null is truly valid, document it clearly and consider making it explicit in the type system (e.g., User | null in TypeScript).
