This is useful for logging errors, displaying error messages to users, or performing cleanup tasks. Here's how you can set up global error handling in JavaScript: Using window.onerror: The window.onerror event handler is a global event handler that fires whenever an uncaught JavaScript error occurs. It allows you to catch and handle unhandled errors at the global level. javascript Copy code window.onerror = function(message, source, lineno, colno, error) { // Log the error or perform other actions console.error("Unhandled error:", message, source, lineno, colno, error); }; The parameters of the window.onerror handler function provide information about the error, such as the error message, the source file where the error occurred, the line number, column number, and the error object itself. Using window.addEventListener('error', handler): You can also use the addEventListener() method to attach an event listener for the error event to the window object. This allows you to handle errors in a more flexible and modern way. javascript Copy code window.addEventListener('error', function(event) { // Log the error or perform other actions console.error("Unhandled error:", event.message, event.filename, event.lineno, event.colno, event.error); }); The error event object contains properties such as message, filename, lineno, colno, and error, which provide information about the error. By setting up global error handling, you can ensure that unhandled errors in your JavaScript code are caught and handled appropriately, improving the robustness and reliability of your application.
