Exceptions · interview question
Why wrap an exception with the original cause instead of replacing it completely?
Multiple choiceHardchapter-6-curatedpremiumexceptionscause-chaining-and-error-context
Answer and explanation
Correct answer
A. To add higher-level context while preserving the technical root cause for debugging
Why
Cause chaining lets higher layers explain what operation failed without erasing the low-level reason. That makes production debugging much easier than replacing the original exception with a vague wrapper.
