Javascript:将两个数组合并为单个对象而不丢失键顺序

Question

我在两个字符串中有一些原始 imdb 数据:

var headers = "ID   imdbID  Title   Year    Rating  Runtime Genre   Released    Director    Writer  Cast    Metacritic  imdbRating  imdbVotes   Poster  Plot    FullPlot    Language    Country Awards  lastUpdated";


const content = "1  tt0000001   Carmencita  1894    NOT RATED   1 min   Documentary, Short      William K.L. Dickson        Carmencita      5.8 1136    http://ia.media-imdb.com/images/M/MV5BMjAzNDEwMzk3OV5BMl5BanBnXkFtZTcwOTk4OTM5Ng@@._V1_SX300.jpg    Performing on what looks like a small wooden stage, wearing a dress with a hoop skirt and white high-heeled pumps, Carmencita does a dance with kicks and twirls, a smile always on her face.           USA     2016-05-04 00:03:31.600000000";

当然，我正在清理制表符和空格等并创建两个数组，如下所示:

const values = content.split(/(\t+)/).filter( (part) => !/\t/.test(part) );

let keys = headers.split(/(\s+)/).filter( (part) => !/\s+/.test(part) );

现在我想keys数组中的键values数组准确映射到values数组中的值。所以我像这样减少:

var result = {};

values.reduce( (acc, val, index) => {
  return result[ keys[index] ] = val; 
}, result);

这给了我一个最终的结果对象，如下所示:

 {
  Cast: "1136",
  Director: "Carmencita",
  Genre: "Documentary, Short",
  ID: "1",
  imdbID: "tt0000001",
  imdbRating: "Performing on what looks like a small wooden stage, wearing a dress with a hoop skirt and white high-heeled pumps, Carmencita does a dance with kicks and twirls, a smile always on her face.",
  imdbVotes: "USA",
  Metacritic: "http://ia.media-imdb.com/images/M/MV5BMjAzNDEwMzk3OV5BMl5BanBnXkFtZTcwOTk4OTM5Ng@@._V1_SX300.jpg",
  Poster: "2016-05-04 00:03:31.600000000",
  Rating: "NOT RATED",
  Released: "William K.L. Dickson",
  Runtime: "1 min",
  Title: "Carmencita",
  Writer: "5.8",
  Year: "1894"
}

正如你所看到的，顺序完全困惑了!如何在数据中获得正确的顺序，以便将 title 键映射到电影标题值等？

我愿意使用像 lodash 这样的库来实现这一目标，但不知道我应该使用什么？这是当前状态的 jsbin 演示:https://jsbin.com/gekawi/edit?js,console

如果您获取带有标签的原始数据，则可以使用它们进行拆分。

var headers = "ID	imdbID	Title	Year	Rating	Runtime	Genre	Released	Director	Writer	Cast	Metacritic	imdbRating	imdbVotes	Poster	Plot	FullPlot	Language	Country	Awards	lastUpdated",
    content = "1	tt0000001	Carmencita	1894	NOT RATED	1 min	Documentary, Short		William K.L. Dickson		Carmencita		5.8	1136	http://ia.media-imdb.com/images/M/MV5BMjAzNDEwMzk3OV5BMl5BanBnXkFtZTcwOTk4OTM5Ng@@._V1_SX300.jpg	Performing on what looks like a small wooden stage, wearing a dress with a hoop skirt and white high-heeled pumps, Carmencita does a dance with kicks and twirls, a smile always on her face.			USA		2016-05-04 00:03:31.600000000",
    headerArray = headers.split(/\t/),
    contentArray = content.split(/\t/),
    object = {};

headerArray.forEach(function (k, i) {
    object[k] = contentArray[i];
});

console.log(object);
