AngularJS에서 체크박스 값을 목록에 효율적으로 바인딩하는 방법은 무엇입니까?

<label ng-repeat="fruitName in fruits">
  <input
    type="checkbox"
    name="selectedFruits[]"
    value="{{fruitName}}"
    ng-checked="selection.indexOf(fruitName) > -1"
    ng-click="toggleSelection(fruitName)"
  > {{fruitName}}
</label>

app.controller('SimpleArrayCtrl', ['$scope', function SimpleArrayCtrl($scope) {

  $scope.fruits = ['apple', 'orange', 'pear', 'naartjie'];
  $scope.selection = ['apple', 'pear'];

  $scope.toggleSelection = function toggleSelection(fruitName) {
    var idx = $scope.selection.indexOf(fruitName);
    idx > -1 ? $scope.selection.splice(idx, 1) : $scope.selection.push(fruitName);
  };
}]);

<label ng-repeat="fruit in fruits">
  <input
    type="checkbox"
    name="selectedFruits[]"
    value="{{fruit.name}}"
    ng-model="fruit.selected"
  > {{fruit.name}}
</label>

app.controller('ObjectArrayCtrl', ['$scope', 'filterFilter', function ObjectArrayCtrl($scope, filterFilter) {

  $scope.fruits = [
    { name: 'apple',    selected: true },
    { name: 'orange',   selected: false },
    { name: 'pear',     selected: true },
    { name: 'naartjie', selected: false }
  ];

  $scope.selection = [];

  $scope.selectedFruits = function selectedFruits() {
    return filterFilter($scope.fruits, { selected: true });
  };

  $scope.$watch('fruits|filter:{selected:true}', function (nv) {
    $scope.selection = nv.map(function (fruit) {
      return fruit.name;
    });
  }, true);
}]);
