如何使用 Javascript/underscorejs 找到包含对象的数组的交集？

我不知道如何找到这组数组的交集：

[
 [
  {"name":"product1","light":"1"},
  {"name":"product2","light":"2"},
  {"name":"product5","light":"5"},
  {"name":"product4","light":"4"}
 ],
 [
  {"name":"product2","light":"2"},
  {"name":"product3","light":"3"},
  {"name":"product4","light":"4"}
 ],[...more arrays with objects]
]

这只是样本数据，真实的集合我有很多变化，但结构是这样的。我希望返回的交集看起来像这样（相交对象的单个数组）：

[
 {"name":"product2","light":"2"},
 {"name":"product4","light":"4"},
]

我与 LoDash 和 Underscore Js 一起尝试过：

_.intersectionObjects = _.intersect = function(array) {
var slice = Array.prototype.slice; // added this line as a utility
var rest = slice.call(arguments, 1);
return _.filter(_.uniq(array), function(item) {
  return _.every(rest, function(other) {
    //return _.indexOf(other, item) >= 0;
    return _.any(other, function(element) { return _.isEqual(element, item); });
  });
});
};

我需要这个，因为我正在尝试使用 knockoutjs 创建一个标签系统。我有一个分类标签按钮的布局，单击时写入“过滤器”可观察数组，剩下的唯一事情就是找到此可观察数组中包含的过滤产品的交集。

请帮助我，我已经连续两天尝试解决这个问题，但缺乏 javascript 知识来解决这个问题。提前致谢！

尝试添加他们应用方法：

  var myArr = [
    [
      {"name":"product1","light":"1"},
      {"name":"product2","light":"2"},
      {"name":"product5","light":"5"},
      {"name":"product4","light":"4"}
    ],
    [
      {"name":"product2","light":"2"},
      {"name":"product3","light":"3"},
      {"name":"product4","light":"4"}
    ]
  ]

  _.intersectionObjects = _.intersect = function(array) {
    var slice = Array.prototype.slice;
    var rest = slice.call(arguments, 1);
    return _.filter(_.uniq(array), function(item) {
      return _.every(rest, function(other) {
        return _.any(other, function(element) {
          return _.isEqual(element, item);
        });
      });
    });
  };

  var myIntersection = _.intersectionObjects.apply(_, myArr);

  for (var i = 0; i < myIntersection.length; i++) {
    console.log(myIntersection[i]);
  }

  // Sample Output:
  // Object {name: "product2", light: "2"}
  // Object {name: "product4", light: "4"}
