Answer
Use default values or ignore unknowns. Frame the concept in practical terms so you can explain it during interview discussion.
To ensure new fields in JSON APIs are non-breaking, provide default values or configure clients to ignore unknown fields. This approach ensures that clients not expecting these fields continue to function correctly. For example, using Jackson, you can annotate your Java objects to ignore unknown properties during deserialization.
