Learning AngularJs Class Manipulation

With ng-class it is possible to set classes, if the value==true
For example, with ng-class="{disabled: isDisabled}" the element gets the class "disabled" only if isDisabled==true.

We can use several classes for one element. In the next example we use ng-class="{strike: strike, bold: bold, red: red}
CSS: .red { color: red; }, and so on.
Checkboxes sets values to true, if checked: input type="checkbox" ng-model="red", ...

$index - in ng-repeat returns index.
We use ng-repeat, to repeat restaurants. By the click on one restaurant, we change the variable 'selectedRow': $scope.selectRestaurant = function(row) {$scope.selectedRow = row;}; Each restaurant has the class ng-class='{selected: $index==selectedRow}', so the selected restaurant gets the class='selected'. Click is implemented with ng-click: ng-click='selectRestaurant($index)'.
