// Angular commands
var newObj = angular.copy(oldObj);
var isEqual = angular.equals([1,'2'], [1,'2', 3]); // Returns: false
$location.search('myQueryString', null); // Remove querystring

// Angular html commands
// $scope.value = true;
<div ng-show="value"></div>

// Pass event along, BAD but works. Don't need to define $event anywhere
<li ng-click="go(image, $event)"/>

$scope.go(image, $event) {
  if ($($event.target).hasClass('gallery')){
    // In case you had nested inputs that you didn't want parent click on
  }
}

// Filter ng-repeat by properties -- i.e. filter by selected items
// filteredImages - doesn't exist, images is my array of data
// _checked is a property images[0]._checked
<li ng-repeat="image in filteredImages = (images | filter:{_checked: true})" ></li>


// Prevent state change
$rootScope.$on('$stateChangeStart', function ( event, toState, toParams, fromState, fromParams ) {
  // Do custom logic here...
  event.preventDefault(); // Will not let the browser change state
});
