Just to illustrate.
This is what you get when you load minified version of Angular (angular.min.js):
Error: $injector:modulerr
Module Error
Failed to instantiate module eduApp due to:
Error: [$injector:modulerr] http://errors.angularjs.org/1.4.7/$injector/modulerr?p0=e...)
at Error (native)

And this is what you get when you use unminified version (angular.js):
Error: $injector:nomod
Module Unavailable
Module 'ui.bootstrap' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
The first error is really painful to solve. The second one is much more easier.
Happy coding!
