es6中怎么将数组转为对象

es6中将数组转为对象的方法

方法1：利用fromEntries()和map()函数

const arr = [
  { key: "id", name: "编号" },
  { key: "name", name: "名称" },
];

const obj = Object.fromEntries(arr.map(item => [item.key, item]));

console.log(obj);

输出

方法2：利用扩展运算符“...”

const arr = [
  { key: "id", name: "编号" },
  { key: "name", name: "名称" },
];

const obj = {...arr} ;

console.log(obj);
