Is it possible to filter angular.js by containment in another array?

Question

So if I have an array:

$scope.letters = 
[{\"id\":\"a\"},
{\"id\":\"b\"},
{\"id\":\"c\"}];

And another array

$scope.filter

You should try something like that:

JS:

angular.module('Test', []);

function Ctrl($scope) {
  $scope.letters = [
    {id: 'a'},
    {id: 'b'},
    {id: 'c'}
  ];

  $scope.filterBy = ['b', 'c', 'd'];

  $scope.filteredLetters = function () {
    return $scope.letters.filter(function (letter) {
      return $scope.filterBy.indexOf(letter.id) !== -1;
    });
  };
}

Ctrl.$inject = ['$scope'];

HTML:

{{letter.id}}

You can try live example.
