使用 lodash 将一个对象扩展到另一个对象

Question

我有一个包含图像数组的对象（只有 ID）。

   var listOfImages = {
      "number-items": 30,
      "pageCount": 0,
      "ids": {
        0: "image1",
        1: "image2"
      }
    };

我也有图片集：

    var images = {
      "image1": {
        "author": "Marc",
        "size": "40kb"
      },
      "image2": {
        "author": "Anthony",
        "size": "60kb"
      },
      "image3": {
        "author": "Anthony",
        "size": "60kb"
      }
    }; image2,
    ]

我想把它们全部结合起来，所以有这样的东西：

var extendedListOfImages = {
  "number-items": 30,
  "pageCount": 0,
  "ids": {
    0: {"id": "image1", "author": "Marc", "size": "40kb"},
    1: {"id": "image2", "author": "Anthony", "size": "60kb"}
  }
};

lodash 的新手，所以如果可能的话，我希望能有更好的解决方案。我现在的解决方案：

  var listOfImages = {
  "number-items": 30,
  "pageCount": 0,
  "ids": {
    0: "image1",
    1: "image2"
  }
};
var images = {
  "image1": {
    "author": "Marc",
    "size": "40kb"
  },
  "image2": {
    "author": "Anthony",
    "size": "60kb"
  },
  "image3": {
    "author": "Anthony",
    "size": "60kb"
  }
};

myIds = _.keyBy(listOfImages.ids);
_.map(myIds, function(key, value){
  myIds[key]= images[key];
});
listOfImages.ids=myIds;
console.log(listOfImages);
