如何根据javascript中的键合并和替换两个数组中的对象？

const arrayList1 = [
    { type: "A", any: 11, other: "ab", props: "1" },
    { type: "B", any: 22, other: "bc", props: "2" }, // same type
    { type: "C", any: 33, other: "df", props: "3" }
];
 
const arrayList2 = [
    { type: "D", any: 44, other: "aa", props: "11" },
    { type: "B", any: 22, other: "bb", props: "2----2" , x: 10}, // same type
    { type: "E", any: 44, other: "cc", props: "33" }
];

result = arrayList2.reduce(function (arr1, arr2) {
  let isMatchFound = false;
  arr1.forEach(function (list) {
    if (arr2.type == list.type) {
      list = Object.assign(list, arr2);
      isMatchFound = true;
    }
  });
  if (!isMatchFound) {
    arr1.push(arr2);
  }
  return arr1;
}, arrayList1);

console.log('result', JSON.stringify(result));

const arrayList1 = [
    { type: "A", any: 11, other: "ab", props: "1" },
    { type: "B", any: 22, other: "bc", props: "2" }, // same type
    { type: "C", any: 33, other: "df", props: "3" }
];
 
const arrayList2 = [
    { type: "D", any: 44, other: "aa", props: "11" },
    { type: "B", any: 22, other: "bb", props: "2----2" , x: 10}, // same type
    { type: "E", any: 44, other: "cc", props: "33" }
];

const result = Object.values(
   [].concat(arrayList1, arrayList2)
     .reduce((r, c) => (r[c.type] = Object.assign((r[c.type] || {}), c), r), {})
);
                 
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
