Tips for detecting and handling errors in user input from the console

Is there a way to catch errors in Chrome's developer tools console when an input throws an error? I attempted using window.addEventListener("error") but it seems that the onerror event listener on window does not capture the console errors.

Answer №1

Why not give a try ... catch block a go? By using this method, console errors will be captured automatically. As per Mozilla DN, this approach is compatible with all modern browsers.

function refError() {
  return a; // This is purposely done for illustration purposes
}

try {
  console.log(refError());
} catch (err) {
  console.log('Caught: ' + err.name);
  console.log('Details: ' + err.message);
  // Handle the error accordingly
}
