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);

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

let arr = {};

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

console.log(arr);

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'));

坐地lodash !

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

下面是如何动态地接受上面的字符串，并将其插入到一个对象:

var stringObject = '[Object { key="11", value="1100", $$hashKey="00X"}, Object { key="22", value="2200", $$hashKey="018"}]';

function interpolateStringObject(stringObject) {
  var jsObj = {};
  var processedObj = stringObject.split("[Object { ");
  processedObj = processedObj[1].split("},");
  $.each(processedObj, function (i, v) {
      jsObj[v.split("key=")[1].split(",")[0]] = v.split("value=")[1].split(",")[0].replace(/\"/g,'');
  });

  return jsObj
}

var t = interpolateStringObject(stringObject); //t is the object you want

在2022年附近，我喜欢这种方法，特别是当对象数组是动态的时，这也是基于@AdarshMadrecha的测试用例场景的建议，

const array = [ 
  { key : '11', value : '1100', $$hashKey : '00X' },
  { key : '22', value : '2200', $$hashKey : '018' }];
  
let obj = {};
array.forEach( v => { obj[v.key] = v.value }) //assign to new object
console.log(obj) //{11: '1100', 22: '2200'}
