[AngularJS] New in Angular 1.3 - Performance Boost with debugInfoEnabled

By default, Angular provides a lot of debug information on the DOM that's only necessary for tools like Protractor and Batarang. Angular 1.3 allows you to turn off the debug information to give your app a simple performance boost.

See: https://docs.angularjs.org/api/ng/provider/$compileProvider
