把单个的对象组合成树结构

function Tree(list: any, parentId: any) {
  const parentObj = {} as any;
  list.forEach((o: any) => {
    parentObj[o.id] = o;
  });
  if (!parentId) {
    return list
      .filter((o: any) => !parentObj[o.parentId])
      .map((o: any) => ((o.childes = Tree(list, o.id)), o));
  } else {
    return list
      .filter((o: any) => o.parentId == parentId)
      .map((o: any) => ((o.childes = Tree(list, o.id)), o));
  }
}
