如何循环并将对象数组转换为具有键值对的对象

Question

我有一个类似这样的对象数组

[
  {name: "John", country: "USA", revision: 1},
  {name: "Mark", country: "England", revision: 0},
  {name: "Bruce", country: "France", revision: 1}
]

我想把它转换成一个带有名字键的键值对的对象，像这样

{
  John : {name: "John", country: "USA", revision: 1},
  Mark : {name: "Mark", country: "England", revision: 0},
  Bruce : {name: "Bruce", country: "France", revision: 1}
}

这是我所做的，但它似乎不起作用

let component = contents.reduce(((content, current}) => {
    content[name] = current;
    return content;
}), {});

这可以使用Array.prototype.reduce func 来完成。

const input = [
  {name: "John", country: "USA", revision: 1},
  {name: "Mark", country: "England", revision: 0},
  {name: "Bruce", country: "France", revision: 1}
];

const output = input.reduce((acc, {name, ...item}) => {
  acc[name] = item;
  return acc;
}, {});
console.log(output);
