Revision 132 of this benchmark created by C E on

Preparation HTML

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

Setup

var html = '';
  
  for (var i = 0; i < 20; i++) {
    html += '<div>Test ' + i + '</div>';
  }
  
  var htmlArray = [];
  
  for (var i = 0; i < 20; i++) {
    htmlArray[i] = '<div>Test ' + i + '</div>';
  }

Test runner

Ready to run.

Testing in

jQuery .append() at end
$('#list').append(html);

  htmlArray2[i] = '<div>Test ' + i + '</div>';
}

$('#list').append(htmlArray2);
ready
javascript innerHTML at end (including array push time)
var html3 = [];

for (var i = 0; i < 20; i++) {
  html3.push('<div>Test ' + i + '</div>');
}

document.getElementById('list').innerHTML = html3.join('');
ready
