javascript - 处理未格式化的数据数组

Question

我正在使用一个函数，该函数返回一些如下数据:

[{url1: "number1"},{url2: "number2"},{url3: "number3"},etc...]

这是我自己编写的函数:

const getNbShares = function() {
    return Promise.map(urls, requestPromise)
                  .map((htmlOnePage, index) => {
                    const $ = cheerio.load(htmlOnePage);
                    const share = $('.nb-shares').html();
                    let shareTuple = {};
                    shareTuple[urls[index]] = share;
                    return shareTuple;
        })
        .catch((e) => console.log('We encountered an error' + e));
}

有没有办法重写这个函数，这样我就有了一个合适的数组对象(最好的解决方案，但更复杂？)或者有没有办法重新格式化我上面的数据数组，这样我就可以得到这样的东西:

[{url:"url1",value: "number1"},{url:"url2",value: "number2"},{url: "url3", value: "number3"},etc...]

是的，只需更改键即可:

const getNbShares = function() {
    return Promise.map(urls, requestPromise)
                  .map((htmlOnePage, index) => {
                    const $ = cheerio.load(htmlOnePage);
                    const share = $('.nb-shares').html();
                    let shareTuple = {};

                    // set `url` to `urls[index]`
                    shareTuple.url = urls[index];

                    // then set the `value` to `share`
                    shareTuple.value = share;

                    return shareTuple;
        })
        .catch((e) => console.log('We encountered an error' + e));
}
