Step by step explanation:

  1. ng-app="myDemoApp", the ngApp directive tells angular that a DOM element is controlled by a specific angular.module named "myDemoApp".
  2. <script src="[//angular include]"> include angular js.
  3. HideShowController function is defined containing another function named toggle which help to hide show the element.
  4. angular.module(...) creates a new module.
  5. .controller(...) Angular Controller and returns the module for chaining;
  6. ng-controller directive is key aspect of how angular supports the principles behind the Model-View-Controller design pattern.
  7. ng-show directive shows the given HTML element if expression provided is true.
  8. ng-hide directive hides the given HTML element if expression provided is true.
  9. ng-click directive fires a toggle function inside controller
