你知道JavaScript的等价物是什么吗？这是我的代码：

def sort_df(datas):
  df_not_sorted = pd.read_json(StringIO(datas))
  df_not_sorted["Date"] = df_not_sorted["Date"].apply(lambda dates: [datetime.fromisoformat(date.rstrip('Z')) for date in dates])
  df_not_sorted["time"] = pd.to_datetime(df_not_sorted["time"])
  df_not_sorted["time"] = df_not_sorted["time"].dt.tz_localize(None)
  df = df_not_sorted.set_index(["Bus", "time"]).sort_index()
  
  return df
