In previous versions of NodeJS / Browser JavaScript, you would have used "callbacks". Which leads to "callback hell".

 *  Fix: Don't drop callbacks on unexpected exceptions. When an interceptor throws an unchecked
    exception the callback is now notified that the call was canceled. The exception is still sent
    to the uncaught exception handler for reporting and recovery.
