Revision 110 of this benchmark created by hin on

Description

This is comparing the runtimes of substr, substring, and slice in a string for large (10000 character) string size.

Setup

var str = Array.apply(null, Array(100)).map (() => String.fromCharCode(Math.round(Math.random() * 100) % 96 + 32)).join('');
    
    var key = String.fromCharCode(Math.round(Math.random() * 100) % 96 + 32));
