比较2个对象数组并用id替换对象

function replaceObjectsWithId(arr1, arr2) {
  let result = [];

  for (let obj1 of arr1) {
    let found = false;

    for (let obj2 of arr2) {
      if (obj1.id === obj2.id) {
        result.push(obj2);
        found = true;
        break;
      }
    }

    if (!found) {
      result.push(obj1);
    }
  }

  return result;
}

// 示例用法
let array1 = [
  { id: 1, name: 'Object 1' },
  { id: 2, name: 'Object 2' },
  { id: 3, name: 'Object 3' }
];

let array2 = [
  { id: 2, name: 'New Object 2' },
  { id: 4, name: 'Object 4' }
];

let newArray = replaceObjectsWithId(array1, array2);
console.log(newArray);
