regex-multi-test-numeric (v2)

Revision 2 of this benchmark created by Dan Dockery on

Description

Multiple regular expression .test() calls using if/else-if, or a single string.match() call. Modified to match on a number, rather than a string, and to test 6 regular expressions, instead of 4.

<script>
  var q1RegExp = /^select istream "Q1/;
  var q2RegExp = /^select istream "Q2/;
  var q3RegExp = /^select istream "Q3/;
  var q4RegExp = /^select istream "Q4/;
  var q5RegExp = /^select istream "Q5/;
  var q6RegExp = /^select istream "Q6/;

  var totalQueryNames = QueryNames.length;

Setup

var QueryIndex = Math.floor(Math.random()*totalQueryNames);
    var QueryName = QueryNames[QueryIndex];
