如何根据相似字段检查合并两个对象数组数据

function mergeArraysBySimilarField(arr1, arr2, similarField) {
  let mergedArray = [];

  arr1.forEach(obj1 => {
    let matchingObj = arr2.find(obj2 => obj2[similarField] === obj1[similarField]);

    if (matchingObj) {
      let mergedObj = { ...obj1, ...matchingObj };
      mergedArray.push(mergedObj);
    } else {
      mergedArray.push(obj1);
    }
  });

  // Add remaining objects from arr2
  let remainingObjs = arr2.filter(obj2 => !arr1.some(obj1 => obj1[similarField] === obj2[similarField]));
  mergedArray.push(...remainingObjs);

  return mergedArray;
}

// 示例用法
const array1 = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Mike' }
];

const array2 = [
  { id: 2, age: 25 },
  { id: 3, age: 30 },
  { id: 4, age: 35 }
];

const mergedArray = mergeArraysBySimilarField(array1, array2, 'id');
console.log(mergedArray);
