error handler

Code failure manager

An error handler is code that responds when something goes wrong in a program—catching exceptions, logging problems, or providing fallback behavior instead of crashing.

Good error handling anticipates failures gracefully: The error handler displays a friendly message when the server is unreachable.

Also called exception handler in some contexts.
