Application error: a client-side exception has occurred (see the browser console for more information).

The amount of articles on HN that render perfectly, then vanish a second later and are replaced by this error message is insane. Yes, I'm using an old unmaintained Android HN reader with a questionable webview. No, that's not an excuse to delete a perfectly rendered from right in front of my eyes.

Sure. But it's not the browser that did that. You see the dialog because the app HANDLED the error condition, and application code displayed an dialog. Had the error not been handled, the browser's behavior is to log a message to the browser console (which you, as a user, never see), and carry on, pretending that the error never happened. So the page would have continued on in some non-functional, or half-functional state.

Yes, of course. My point was more that modern javascript developers have taken that away from us.
