无法对嵌套json中的元素进行排序

我的json结构是这样的：

0:
  day: "2020-03-14"
  total: {confirmed: 81, recovered: 9, deaths: 2, active: 70}
  statewise: Array(37)
    0: {state: "Andaman and Nicobar Islands", confirmed: 0, recovered: 0, deaths: 0, active: 0}
    1: {state: "Andhra Prad ......

每天记录这些阵列。所以对于每个日期，我都有这种结构。

171-172行：

  var data = json_data.data.history[7].statewise;
  var data1 = json_data.data.history

最初，我试图使用特定的日期并绘制条形图。但是现在，我无需手动进行尝试。如果日期匹配此日期，则使用过滤器获取此日期数组。

296-310行：

 let yearSlice = data1.filter(function(d) {
  // log("d.date::::::::",d, d.day, new Date(d.day), year, (new Date(d.day).getTime()===year.getTime()));
  return new Date(d.day).getTime()===year.getTime();
 })

  .sort(function(a,b){
    log("aaaaaaaaaA:",a);
    log("astatewise:", a.statewise);
    return d3.descending(a.confirmed, b.confirmed) ;})
  .slice(0, top_n);


  yearSlice.forEach(function(d,i)
  { log("dddddddddddD:",d.statewise[i].confirmed,i);
    return d.rank = i});

我试图按任何情况排序。因此，第一个元素将为我提供最大案例数的状态。然后我将对前10个州进行排名。

But this sort function doesn't even work as there is no console.log output. Filtering does work but not the sort thing.

有人可以帮我吗？
