Error Handling
Error handling is a programming concept and practice that involves anticipating, detecting, and responding to errors or exceptions that occur during software execution. It ensures programs can gracefully manage unexpected conditions, such as invalid input, network failures, or resource unavailability, without crashing. This includes mechanisms like try-catch blocks, error codes, and logging to maintain stability and provide useful feedback.
Developers should learn error handling to build robust, reliable applications that can withstand real-world issues like user mistakes or system failures. It is essential in production environments to prevent crashes, improve user experience by offering meaningful error messages, and aid debugging through detailed logs. Use cases include web APIs handling malformed requests, databases managing connection drops, and financial software ensuring transaction integrity.
