It centralizes error handling, improving maintainability and reliability.
Exception propagation allows errors to bubble up to a layer where they can be handled appropriately, often in a centralized manner. In a complex e-commerce system, a network failure during order processing might be propagated to a higher layer that manages retry logic or alternative workflows, rather than being caught and ignored at a lower layer, ensuring reliability and consistent application behavior.
