javascript - 如何将包含对象的对象转换为数组的数组？

Question

如何转换此数据结构:

const data = {
            0: {
                campaign_lead_id: 2,
                date: "2017-11-11T22:19:33.538000+00:00",
                campaign_name: "IOT course fall 2017",
                influencer_name: null,
                influencer_email: "test_user_1@key"
            },
            1: {
                campaign_lead_id: 1,
                date: "2017-11-09T20:43:26.953000+00:00",
                campaign_name: "IOT course fall 2017",
                influencer_name: null,
                influencer_email: "test_user_1@key"
            }
        }

到数组的数组，其中第一个数组包含键名称，其他数组包含键值，如下所示:

const CSVdata = [ 
            ['campaign_lead_id', 'date', 'campaign_name', 'influencer_name', 'influencer_email'],
            ['2', '2017-11-11T22:19:33.538000+00:00', 'IOT course fall 2017', null, 'test_user_1@2key.co'],
            ['1', '2017-11-09T20:43:26.953000+00:00', 'IOT course fall 2017', null, 'test_user_1@2key.co']
        ];

下面是我认为您可能正在寻找的代码。
将对象传递给 makeArray 函数，它将返回所需的数组。

const data = {
            0: {
                campaign_lead_id: 2,
                date: "2017-11-11T22:19:33.538000+00:00",
                campaign_name: "IOT course fall 2017",
                influencer_name: null,
                influencer_email: "test_user_1@key"
            },
            1: {
                campaign_lead_id: 1,
                date: "2017-11-09T20:43:26.953000+00:00",
                campaign_name: "IOT course fall 2017",
                influencer_name: null,
                influencer_email: "test_user_1@key"
            }
        };
function makeArray(data){
var initialKeys = Object.keys(data);
var answer = [Object.keys(data[initialKeys[0]])];
      for(let i=0;i<initialKeys.length;i++) {
      answer.push(Object.values(data[i]));
}
return answer;
}
const CSVdata = makeArray(data);
console.log(CSVdata);

注意:仅对对象的对象有效。
