Summary

The AngularJS controller contains JavaScript functions that govern data and behavior for a display part. You paste it into HTML with the ng-controller attribute, then access the data through $scope. To avoid global name collisions, it is best to write the controller in the form of an array function with the dependencies injected.

Key points

Ng-controller attaching the controller to the DOM part
$scope becomes the data bridge between view and controller
Use the syntax of the dependency array to be safe against minification
