如何将多个对象索引转换为嵌套数组？

function convertToNestedArray(indexes) {
  let nestedArray = [];

  for (let index of indexes) {
    let keys = index.split('.');
    let currentLevel = nestedArray;

    for (let i = 0; i < keys.length; i++) {
      let key = keys[i];
      let existingLevel = currentLevel.find(item => item.key === key);

      if (!existingLevel) {
        existingLevel = { key: key, value: {} };
        currentLevel.push(existingLevel);
      }

      if (i === keys.length - 1) {
        existingLevel.value = index;
      }

      currentLevel = existingLevel.value;
    }
  }

  return nestedArray;
}

// 示例用法
let indexes = ['a.b.c', 'a.b.d', 'a.e', 'f'];
let result = convertToNestedArray(indexes);
console.log(result);

[
  {
    key: 'a',
    value: {
      key: 'b',
      value: {
        key: 'c',
        value: 'a.b.c'
      },
      {
        key: 'd',
        value: 'a.b.d'
      }
    }
  },
  {
    key: 'a',
    value: {
      key: 'e',
      value: 'a.e'
    }
  },
  {
    key: 'f',
    value: 'f'
  }
]
