Using try-catch blocks in JavaScript enables robust error handling that prevents application crashes and provides graceful failure management. As the creator of CoreUI with over 25 years of JavaScript development experience, I’ve implemented comprehensive error handling in countless production applications and component libraries. From my expertise, the most effective approach is wrapping potentially error-prone code in try blocks and handling exceptions in catch blocks with appropriate fallback strategies. This pattern ensures applications remain stable and provide meaningful feedback when unexpected errors occur.
