使用物件和陣列將物件陣列映射到物件陣列

我有一個物件

   const response =  {
        "message": "story records found successfully",
        "result": [
            {
                "created_AT": "Thu, 13 Jan 2022 17:37:04 GMT",
                "created_BY": "avinash",
                "dateTime": "Thu, 13 Jan 2022 17:37:04 GMT",
                "deleted_BY": "",
                "flag": 0,
                "project_ID": "infobot1234",
                "stories": {
                    "steps": [
                        {
                            "intent": "test"
                        },
                        {
                            "action": "uttence_test_heading"
                        },
                        {
                            "intent": "fruits"
                        },
                        {
                            "intent": "testintent"
                        },
                        {
                            "action": "utter_txt1234"
                        },
                        {
                            "action": "uttence_test_heading"
                        },
                        {
                            "action": "utter_txt1234"
                        },
                        {
                            "intent": "test"
                        },
                        {
                            "intent": "fruits"
                        },
                        {
                            "action": "uttence_test_heading"
                        },
                        {
                            "intent": "my_localities12333qqqwq"
                        }
                    ],
                    "story": "happy path rdedd"
                },
                "stories_ID": "f5728c4f-3717-40c2-8419-265d5d59bfd1",
                "updated_BY": "",
                "user_ID": "av1234"
            }
        ],
        "status_code": 0
    }

由此我必須創建一個類似的結構，所以我的預期輸出是

const data = [
                  {intent: 'test', actions:['uttence_test_heading']},
                  {intent:'fruits', actions:[]},
                  {intent:"testintent", actions:["utter_txt1234","uttence_test_heading","utter_txt1234"]},
                  {intent:"test", actions:[]},
                  {intent:"fruits", actions:["uttence_test_heading"]},
                  {intent: "my_localities12333qqqwq", actions:[]}
                 ]

我能得到的最接近的是使用response.result[0].stories.steps它給我的結果

[{
  intent: "test"
}, {
  action: "uttence_test_heading"
}, {
  intent: "fruits"
}, {
  intent: "testintent"
}, {
  action: "utter_txt1234"
}, {
  action: "uttence_test_heading"
}, {
  action: "utter_txt1234"
}, {
  intent: "test"
}, {
  intent: "fruits"
}, {
  action: "uttence_test_heading"
}, {
  intent: "my_localities12333qqqwq"
}]

我怎樣才能達到我的預期結果我必須使用一些條件或類似的東西Object.keys然后應用任何條件，因為對于每個意圖都有一個動作，如果沒有動作那么它應該是一個空陣列。

我怎樣才能達到我的預期結果，請指導！

uj5u.com熱心網友回復：

您需要使用陣列方法遍歷每個陣列元素reduce，并檢查該元素是否是一個意圖。如果是，則將新物件推送到結果陣列，如果不是，只需使用以下.at()方法將新元素推送到最后一個索引意圖的操作陣列：

const steps = [
  {"intent": "test"},
  {"action": "uttence_test_heading"},
  {"intent": "fruits"},
  {"intent": "testintent"},
  {"action": "utter_txt1234"},
  {"action": "uttence_test_heading"},
  {"action": "utter_txt1234"},
  {"intent": "test"},
  {"intent": "fruits"},
  {"action": "uttence_test_heading"},
  {"intent": "my_localities12333qqqwq"}
];

const result = steps.reduce((acc, e) => {
  if (Object.keys(e)[0] === "intent") {
    acc.push({ ...e, actions: [] });
  }else {
    acc.at(-1).actions.push(e.action)
  }
  
  return acc;
}, []);

console.log(result)
