Revision 3 of this benchmark created on

Description

comparing two simple approaches to string searching in a list

Preparation HTML

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

Setup

var list = [];
    for (var i=0; i < 5000; i++)
    {
        var rand_string = '';
        for (var j=0; j < 6; j++)
        {
             var seed = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890';
             rand_string += seed[Math.floor(Math.random()*62)];
        }
        list.push(rand_string);
    }
    list.push('stljs');
