如何对数组进行排序，以按降序而不是字母顺序显示covid病例国家的数据？

Question

此代码正在使用API获取Covid19统计数据的数据，目前其按字母顺序显示所有国家的covid病例数据......我想按降序显示数据，即病例较多的国家应该在表中排在第一位$.ajax({  url: "https://api.covid19api.com/summary",  type: "GET",  dataType: 'JSON',  success: function(data) {    console.log(data);    console.log(data.Countries);    var sno = 1;    $.each(data.Countries, function(key, value) {      $("#country-wise").append("<tr>" +        "<td>" + sno + "</td>" +        "<td>" + value.Country + "</td>" +        "<td>" + value.NewConfirmed + "</td>" +        "<td>" + value.NewDeaths + "</td>" +        "<td>" + value.NewRecovered + "</td>" +        "<td>" + value.TotalConfirmed + "</td>" +        "<td>" + value.TotalDeaths + "</td>" +        "<td>" + value.TotalRecovered + "</td>" +        "</tr>");      sno++;    });  }});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><table id="country-wise"></table>

使用 的方法。sortArray

$.ajax({

  url: "https://api.covid19api.com/summary",

  type: "GET",

  dataType: 'JSON',

  success: function(data) {

    console.log(data);

    console.log(data.Countries);

    data.Countries.sort((a, b) => b.TotalConfirmed - a.TotalConfirmed);

    var sno = 1;

    $.each(data.Countries, function(key, value) {

      console.log(key + ":" + value);

      $("#country-wise").append("<tr>" +

        "<td>" + sno + "</td>" +

        "<td>" + value.Country + "</td>" +

        "<td>" + value.NewConfirmed + "</td>" +

        "<td>" + value.NewDeaths + "</td>" +

        "<td>" + value.NewRecovered + "</td>" +

        "<td>" + value.TotalConfirmed + "</td>" +

        "<td>" + value.TotalDeaths + "</td>" +

        "<td>" + value.TotalRecovered + "</td>" +

        "</tr>");

      sno++;

    });

  }

});
