javascript - 向 JSON 添加新属性？

Question

我有 JSON 数据，我想更新其中的项目。

如何为 Controller 中的所有 ID 添加 name 属性？

{ 
  "games" : [
      { "id":["1"] },
      { "id":["2"] },
      { "id":["3"] },
      { "id":["4"] },
      { "id":["5"] },
      { "id":["6"] }
   ]
}

应该是:

{ 
  "games" : [
      { "id":["1"],"name":"1" },
      { "id":["2"],"name":"2" },
      { "id":["3"],"name":"3" },
      { "id":["4"],"name":"4" },
      { "id":["5"],"name":"5" },
      { "id":["6"],"name":"6" }
   ]
}

for (var i = 1; i <= games.length; i++) {
    games[].name = i;
}

使用forEach 遍历data.games 数组的每一项，然后使用game 简单地添加name 属性。 name = game.id[0].

const data = { 
  "games" : [
      { "id":["1"] },
      { "id":["2"] },
      { "id":["3"] },
      { "id":["4"] },
      { "id":["5"] },
      { "id":["6"] }
   ]
};

data.games.forEach(game => game.name = game.id[0]);

console.log(data);
