Single vs. Multiple jQuery Append

Benchmark created by Stephen on

Description

You can chain $.append(foo).append(bar).append(baz); in jQuery but is there a performance gain by doing the append() in a single step?

Preparation HTML

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<table id="myTable"></table>

Setup

var loopCount = 100;

Test runner

Ready to run.
