get count of items with some property in an array

Question

I have an array of objects as follow.

$scope.students = [{\'isSelected\': true},
    {\'isSelected\': true},
    {\'isSelected\': false},
    {\'isSelected\':         


        

Answer 1

There is another way to do this: the AngularJS filters. You can write this:

var selectedCount = $filter('filter')($scope.students, { isSelected: true }).length;
