 7 request.responseType = 'json';
 8 request.send();
 9 
10 request.onload = function() {
11   var constellations = request.response;
12   //var constellations = JSON.parse(constellationsText);
13   populateHeader(constellations);
14   showcon(constellations);
15 }
16 
17 
18 function populateHeader(jsonObj) {
19   var myH1 = document.createElement('h1');
20   myH1.textContent = jsonObj['mainname'];
21   header.appendChild(myH1);

27 
28 function showcon(jsonObj) {
29   var con = jsonObj['members'];
30 
31   for (var i = 0; i < con.length; i++) 
32   { var myArticle = document.createElement('article');
33     var myH2 = document.createElement('h2');
