How to make the following JavaScript code work and result in a list of names and ages inside the element with ID "myDivId" :

<div id="myDivId">No results yet</div>
<script>
new PersonPrinter("myDivId",[{"name":"Joe","age":"23"}      
{"name":"Sam","age":"31"}]).render();
</script>`

Answer 1

In the PersonPrinter render function you need to update the div

PersonPrinter.prototype.render = function(id,data) {
var elem = document.elementById(id);
for (var i =0;i <data.length;i++) {

var d = dcoument.createElement('div');
d.appendChild(document.createTextNode('Name'+data.name +'  Age:'+data.age');
elem.appendChild(d);`enter code here`
}
}
