Revision 26 of this benchmark created on

Description

Longer StringsTests to determine which function is faster for detecting whether a string matches a regex pattern.

Setup

var abcRegex = /abc/;
    String.prototype.test = function(re){ return re.test(this); };
    String.prototype.test2 = function(re){ return this.search(re)>=0; };
    
    function getString() {
        return "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxabcxxxxxxabcxx";
    }
