Javascript 如果对象中的值与另一个对象属性匹配，如何获取这些值

下面我有一个对象，我想对其进行迭代，如果特定的object properties.title与任何其他对象相同，请使用作者名称并将其添加到一个新对象中，我认为将其添加到一个新对象中会更容易

业务1

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "geometry": {
                "type": "Point",
                "coordinates": [
                    -89.535,
                    34.3654
                ]
            },
            "place_name": "University, Mississippi, United States",
            "properties": {
                "title": "Using Adversarial Autoencoders for Multi-Modal Automatic Playlist Continuation",
                "authorTitle": "Florian Mai"
            }
        },
        {
            "type": "Feature",
            "geometry": {
                "type": "Point",
                "coordinates": [
                    10.14,
                    54.33
                ]
            },
            "place_name": "24105, Kiel, Schleswig-Holstein, Germany",
            "properties": {
                "title": "Using Adversarial Autoencoders for Multi-Modal Automatic Playlist Continuation",
                "authorTitle": "Iacopo Vagliano"
            }
        },
        {
            "type": "Feature",
            "geometry": {
                "type": "Point",
                "coordinates": [
                    10.14,
                    54.33
                ]
            },
            "place_name": "pretend place",
            "properties": {
                "title": "new title",
                "authorTitle": "joe blogs"
            }
        }

    ],
    "properties": "",
    "authors": ""
}

我想改进的对象

var improvedObj = {

    obj1 = {
      title:'Using Adversarial Autoencoders for Multi-Modal Automatic Playlist Continuation"',
      authorList: 'Florian Mai,Iacopo Vagliano'
    },
    obj2 = {
        title:'new title',
        authorList: 'joe blogs
  }

}

我试过的

extractorArray = []

for(i=0; i<business1.features.length;i++){
extractorArray.push(business1.features[i].properties)
}
console.log('extractor', extractorArray)

var extractedValues = extractorArray.map((title) => (title));
var extractedAuthor = extractorArray.map((authorTitle) => (authorTitle))

    var improvedObj = {

      objList : {
        title:extractedValues,
        authorList: extractedAuthor
      }
    }

上面介绍了每个特性，获取其属性并将其推送到提取器阵列，以便我可以在其上使用.map函数。现在我的想法不起作用了，因为我只是从对象中的数组中复制。如果标题相同，就拿它的作者来说。我猜你改进的对象实际上是数组，如果我错了，请纠正我。下面这些应该对你有用

const authorsByBook = k.features.map(feature => feature.properties).reduce((byTitle, feature) => {
    if(!byTitle[feature.title]) byTitle[feature.title] = [];
    byTitle[feature.title].push(feature.authorTitle);
return byTitle
}, {})

const improvedObject = Object.keys(authorsByBook).map(title => ({ title, authorList: authorsByBook[title].join(',')}))

第一部分循环列表并创建结构对象{title:authors[]}。在那之后，基于标题将其分解为带有对象{title，}

的数组，我无法确切理解您想要做什么。是否要获取具有相同名称的所有对象？或者，您只需浏览列表，检查给定一个对象A，另一个对象是否具有与A相同的属性。标题？第二个建议。我想通读一下，如果另一个对象与标题相同，则将作者附加到该对象上。并将作者的标题添加到新对象中。同时获得坐标是否会太难和太粗糙？所以在新的阵列中会有一组坐标，就像作者一样？
