## Description
|
|
<section id='description'>
|
|
So far, you have created a set of characters that you want to match, but you could also create a set of characters that you do not want to match. These types of character sets are called <code>negated character sets</code>.
|
|
To create a <code>negated character set</code>, you place a <code>caret</code> character (<code>^</code>) after the opening bracket and before the characters you do not want to match.
|
|
For example, <code>/[^aeiou]/gi</code> matches all characters that are not a vowel. Note that characters like <code>.</code>, <code>!</code>, <code>[</code>, <code>@</code>, <code>/</code> and white space are matched - the negated vowel character set only excludes the vowel characters.
