如何根据2个键合并数组对象？

function mergeObjectsByKey(arr1, arr2, key1, key2) {
  let result = [];

  arr1.forEach(obj1 => {
    let value1 = obj1[key1];
    let matched = false;

    arr2.forEach(obj2 => {
      let value2 = obj2[key2];

      if (value1 === value2) {
        let mergedObj = { ...obj1, ...obj2 };
        result.push(mergedObj);
        matched = true;
      }
    });

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

  return result;
}

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

let array2 = [
  { id: 1, age: 25 },
  { id: 2, age: 30 },
  { id: 4, age: 35 }
];

let mergedArray = mergeObjectsByKey(array1, array2, 'id', 'id');
console.log(mergedArray);
