I using now this function for fetch data by continent name, so dont worry if order change again ??
const continentToAbbr = {"Europe": "eu", "Asia": "as", "North America": "na", "South America": "sa", "Africa": "af", "Australia/Oceania": "oa"};
$.getJSON(urlc, function(data, status) {
for (const item of data) {
$("#cov-" + continentToAbbr[item["continent"]] + "-cases").append(item["cases"]).digits();
$("#cov-" + continentToAbbr[item["continent"]] + "-recoverd").append(item["recovered"]).digits();
$("#cov-" + continentToAbbr[item["continent"]] + "-dead").append(item["deaths"]).digits();
$("#cov-" + continentToAbbr[item["continent"]] + "-active").append(item["active"]).digits();
$("#cov-" + continentToAbbr[item["continent"]] + "-today-case").append(item["todayCases"]).digits();
$("#cov-" + continentToAbbr[item["continent"]] + "-today-deaths").append(item["todayDeaths"]).digits();
$("#cov-" + continentToAbbr[item["continent"]] + "-critical").append(item["critical"]).digits();
$("#cov-" + continentToAbbr[item["continent"]] + "-tests").append(item["tests"]).digits();
