Apple Serving debug JavaScript code full of bugs

Visit https://supportpayment.apple.com/app and open your developer window on the browser. You'll have a rare opportunity to see all the debug code and a bunch of petty errors on your console.

This is AngularJS code in production. If you're wondering how it actually works in prod, this could be a reference, either in a good or a bad way.

The errors I'm seeing are looking like a lot of string interpolation errors, and in error handling. The funny thing is, the error notifier module itself has an error in the URL generation, so the error is actually never sent to server.
