let array = [
  { key: "key1", value: "value1" },
  { key: "key2", value: "value2" },
];

let arr = {};

arr = array.map((event) => ({ ...arr, [event.key]: event.value }));

console.log(arr);

这应该做到:

Var数组= [ {key: 'k1'， value: 'v1'}， {key: 'k2'， value: 'v2'}， {键:'k3'，值:'v3'} ]; Var mapped = array。Map (item => ({[item。关键:项目。Value})); var newObj =对象。分配({},……映射); console.log (newObj);

var newObj = Object.assign({}, ...(array.map(item => ({ [item.key]: item.value }) )));

坐地lodash !

const obj = _.keyBy(arrayOfObjects, 'keyName')

你可以使用mapKeys lodash函数。只有一行代码!

请参考这个完整的代码示例(复制粘贴到repl。它或类似):

import _ from 'lodash';
// or commonjs:
// const _ = require('lodash');

let a = [{ id: 23, title: 'meat' }, { id: 45, title: 'fish' }, { id: 71, title: 'fruit' }]
let b = _.mapKeys(a, 'id');
console.log(b);
// b:
// { '23': { id: 23, title: 'meat' },
//   '45': { id: 45, title: 'fish' },
//   '71': { id: 71, title: 'fruit' } }

使用Underscore.js:

var myArray = [
  Object { key="11", value="1100", $$hashKey="00X"},
  Object { key="22", value="2200", $$hashKey="018"}
];
var myObj = _.object(_.pluck(myArray, 'key'), _.pluck(myArray, 'value'));

你可以在一行中将数组的对象合并为一个对象:

const obj = Object.assign({}, ...array);
