regex-multi-test-random (v3)

Revision 3 of this benchmark created by MoonScript on

Description

Multiple regular expression .test() calls using if/else-if, or a single string.match() call. Modified to randomly grab a different string for every loop iteration, instead of using the same string for each test.

Preparation HTML

<script>
  var q1RegExp = /^select hostheader,referer,firstbyte/;
  var q2RegExp = /^select "Q1/;
  var q3RegExp = /^select "Q2/;
  var q4RegExp = /^select "Q3/;
  var singleRegExp = /^select ("Q\d+|hostheader,referer,firstbyte)/;
  var QueryNames = ['select hostheader,referer,firstbyte','select "Q1','select "Q2','select "Q3'];
  var totalQueryNames = QueryNames.length;
