Javascript展平具有对象和重命名属性的深度嵌套数组

function flattenArrayWithObjectAndRenameProperties(arr, prefix = '') {
  let result = [];

  arr.forEach(item => {
    let newPrefix = prefix ? `${prefix}.${item.key}` : item.key;

    if (Array.isArray(item.value)) {
      result = result.concat(flattenArrayWithObjectAndRenameProperties(item.value, newPrefix));
    } else if (typeof item.value === 'object') {
      let flattenedObject = {};
      for (let key in item.value) {
        flattenedObject[`${newPrefix}.${key}`] = item.value[key];
      }
      result.push(flattenedObject);
    } else {
      result.push({ [newPrefix]: item.value });
    }
  });

  return result;
}

// 示例嵌套数组
const nestedArray = [
  { key: 'a', value: 1 },
  { key: 'b', value: [ { key: 'c', value: 2 }, { key: 'd', value: [ { key: 'e', value: 3 } ] } ] },
  { key: 'f', value: { g: 4, h: 5 } }
];

console.log(flattenArrayWithObjectAndRenameProperties(nestedArray));

function safeFlattenArray(arr) {
  return arr.reduce((acc, val) => acc.concat(Array.isArray(val) ? safeFlattenArray(val) : val), []);
}

function flattenWithPrefix(arr, prefix = '') {
  return arr.reduce((acc, val) => {
    let newPrefix = prefix ? `${prefix}.${val.key}` : val.key;
    if (val.value && typeof val.value === 'object') {
      acc.push(...flattenWithPrefix(val.value, newPrefix));
    } else {
      acc.push({ [newPrefix]: val.value });
    }
    return acc;
  }, []);
}
