如何在angularjs中从包含json数组的json对象中获取特定值

var data = {
  "users": [
    {
      "name": "John",
      "age": 25
    },
    {
      "name": "Jane",
      "age": 30
    },
    {
      "name": "Bob",
      "age": 35
    }
  ]
};

var targetName;
data.users.forEach(function(user) {
  if (user.age === 30) {
    targetName = user.name;
  }
});

<div ng-app="myApp" ng-controller="myCtrl">
  <p>特定值: {{targetName}}</p>
</div>

angular.module('myApp', [])
  .controller('myCtrl', function($scope) {
    $scope.targetName = targetName;
  });
