<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<div id="list" style="display:none">
</div>

Setup

var len = 20;

Test runner

Ready to run.

Testing in
TestOps/sec
jquery .append()
var list = $('#list');
for (var i = 0; i < len; i++) {
  var html = '<div>Test ' + i + '</div>';
  list.append(html);
}
ready
jQuery .html()
var html = '';
for (var i = 0; i < len; i++) {
  html += '<div>Test ' + i + '</div>';
}

$('#list').html(html);
ready
native innerHTML
var list = document.getElementById('list');
for (var i = 0; i < len; i++) {
  list.innerHTML = list.innerHTML + '<div>Test ' + i + '</div>';
}
ready
native DOM create & append
var list = document.getElementById('list');
var div = document.createElement("div");
for (var i = 0; i < len; i++) {
  var div = document.createElement("div");
div.appendChild(document.createTextNode("Test " + i));
list.appendChild(div);
}
 
ready
Jquery append all at once
var list = $('#list');
list.append(
'<div>Test ' + 1 + '</div>',
'<div>Test ' + 2 + '</div>',
'<div>Test ' + 3 + '</div>',
'<div>Test ' + 4 + '</div>',
'<div>Test ' + 5 + '</div>',
'<div>Test ' + 6 + '</div>',
'<div>Test ' + 7 + '</div>',
'<div>Test ' + 8 + '</div>',
'<div>Test ' + 9 + '</div>',
'<div>Test ' + 10 + '</div>'
