用JavaScript重新构建这个JSON对象

Question

目前，我的JSON对象如下所示：

[
  ["GB", "gib", "gigabyte", "gigabytes"],
  ["MB", "mib", "megabyte", "megabytes"],
  ["Television", " Televisions", " TV", " TVs"],
  ["tryouts", "tryout", "tests", "test", "trial", "experiment"],
  ["football", "soccer", "Fussball"]
];

我最后想看到的是一个新的对象，它看起来像这样：

[
  {
    synonyms: "GB, gib, gigabyte, gigabytes"
  },
  {
    synonyms: "MB, mib, megabyte, megabytes"
  },
  {
    synonyms: "Television, Televisions, TV, TVs"
  },
  {
    synonyms: "tryouts, tryout, tests, test, trial, experiment"
  },
  {
    synonyms: "football, soccer, Fussball"
  }
];

任何帮助都是非常感谢的。

Answer 1

使用.map()的解决方案

var myArray = [
    ["GB", "gib", "gigabyte", "gigabytes"],
    ["MB", "mib", "megabyte", "megabytes"],
    ["Television", " Televisions", " TV", " TVs"],
    ["tryouts", "tryout", "tests", "test", "trial", "experiment"],
    ["football", "soccer", "Fussball"]
];

var synonymArray = myArray.map(function(list) {
    return {
        synonyms: list.join(", ")
    }
})

Answer 2

使用方法映射(Objects/Array/map)可以很容易地做到这一点。

input = [
  ["GB", "gib", "gigabyte", "gigabytes"],
  ["MB", "mib", "megabyte", "megabytes"],
  ["Television", " Televisions", " TV", " TVs"],
  ["tryouts", "tryout", "tests", "test", "trial", "experiment"],
  ["football", "soccer", "Fussball"]
];

output = input.map(function(d) {return {'synonyms':d.join(', ')};});

document.write(JSON.stringify(output));
console.log(output);

Answer 3

使用for循环并连接：

var newObject = [];
for (var i in originalArray) {
  var originalItem = originalArray[i];
  var textList = originalItem.join(',');
  newObject.push({synonyms:textList});
}
