exec() vs match() vs test() vs search() vs indexOf() (v17)

Revision 17 of this benchmark created on

Description

Tests 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; };

Test runner

Ready to run.
