jQuery append vs html vs innerHTML list performance (v116)

Revision 116 of this benchmark created on

Description

Just a simple example showing the speed difference between populating a list with .append() & .html() and innerHTML

Preparation HTML

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<div id="list" style="visibility:hidden;position:absolute;">
</div>

Setup

var len = 400;

Test runner

Ready to run.

Testing in
TestOps/sec
jquery .append()
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
javascript innerHTML
var list = document.getElementById('list');
for (var i = 0; i < len; i++) {
  list.innerHTML = list.innerHTML + '<div>Test ' + i + '</div>';
}
ready
Concat
var html = [];
for (var i = 0; i < len; i++) {
  html.push('<div>Test ' + i + '</div>');
}

document.getElementById('list').innerHTML = html.join('');
ready
Why Use an Array
var html = '';
for (var i = 0; i < len; i++) {
  html+='<div>Test ' + i + '</div>';
}

document.getElementById('list').innerHTML = html;
ready
