Use case: quiz type (True/False or Multiple/Choice) and content are loaded from Loading Json file asynchronously – using angular promise for $http request – after we resolve the promise (then), we can call two functions: display received data (success), and error handling (failed).

A neat method available in AngularJS: promises. Promises are great as explained here (Shawn Wildermuth’s Blog) and  here (spion), promises are “throw-safe” (where callbacks are not).
