Describe a situation where using error types would be advantageous over sentinel errors.

  • When you need to convey additional context about the error.
  • When you want to return predefined constants for errors.
  • When you want to provide a stack trace for the error.
  • When you need to log the error.
Using error types is advantageous when you need to convey additional context about the error. Sentinel errors are simple constants used to represent errors, whereas error types can carry more information like error messages, error codes, and even context-specific data. This additional information is crucial for debugging and providing meaningful feedback to users or other developers consuming your code.
