如何转换这两个数据结构？

const array = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
  { id: 3, name: 'Charlie' }
];

const object = {
  1: { id: 1, name: 'Alice' },
  2: { id: 2, name: 'Bob' },
  3: { id: 3, name: 'Charlie' }
};

const object = array.reduce((acc, item) => {
  acc[item.id] = item;
  return acc;
}, {});

const object = {
  1: { id: 1, name: 'Alice' },
  2: { id: 2, name: 'Bob' },
  3: { id: 3, name: 'Charlie' }
};

const array = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
  { id: 3, name: 'Charlie' }
];

const array = Object.values(object);

const nestedObject = {
  a: { b: { c: 1 } },
  d: { e: 2 }
};

const flatObject = {
  'a.b.c': 1,
  'd.e': 2
};

function flattenObject(obj, parentKey = '', result = {}) {
  for (const key in obj) {
    if (obj.hasOwnProperty(key)) {
      const newKey = parentKey ? `${parentKey}.${key}` : key;
      if (typeof obj[key] === 'object' && !Array.isArray(obj[key])) {
        flattenObject(obj[key], newKey, result);
      } else {
        result[newKey] = obj[key];
      }
    }
  }
  return result;
}

const flatObject = flattenObject(nestedObject);

const array = [
  { id: 1, name: 'Alice', age: 25 },
  { id: 2, name: 'Bob', age: 30 },
  { id: 3, name: 'Charlie', age: 35 }
];

const formattedArray = [
  { key: 1, label: 'Alice', value: 25 },
  { key: 2, label: 'Bob', value: 30 },
  { key: 3, label: 'Charlie', value: 35 }
];

const formattedArray = array.map(item => ({
  key: item.id,
  label: item.name,
  value: item.age
}));
