按键减少数组对象并返回嵌套对象

function reduceArrayObjectsByKey(array, key) {
  const result = {};

  array.forEach(obj => {
    const keyValue = obj[key];
    if (!result[keyValue]) {
      result[keyValue] = [];
    }
    result[keyValue].push(obj);
  });

  return result;
}

// 示例用法
const array = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
  { id: 1, name: 'Charlie' }
];
const key = 'id';

const nestedObject = reduceArrayObjectsByKey(array, key);
console.log(nestedObject);

{
  1: [
    { id: 1, name: 'Alice' },
    { id: 1, name: 'Charlie' }
  ],
  2: [
    { id: 2, name: 'Bob' }
  ]
}
