Missing error handling
Errors occur without proper handling, leading to crashes.
[ FAQ1 ]
What is missing error handling?
Missing error handling occurs when a program fails to anticipate and manage errors or exceptional situations that can arise during execution. Without proper handling—such as using
try-catch blocks or managing promise rejections—errors can propagate unchecked, causing applications to crash, fail silently, or behave unpredictably. Poor or absent error handling also hinders debugging, troubleshooting, and stability by obscuring underlying issues and preventing graceful recovery from error conditions.[ FAQ2 ]
