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 negated character sets. To create a negated character set, you place a caret character (^) after the opening bracket and before the characters you do not want to match. For example, /[^aeiou]/gi matches all characters that are not a vowel. Note that characters like ., !, [, @, / and white space are matched - the negated vowel character set only excludes the vowel characters.

Instructions

Create a single regex that matches all characters that are not a number or a vowel. Remember to include the appropriate flags in the regex.

Tests

tests:
  - text: Your regex <code>myRegex</code> should match 9 items.
    testString: 'assert(result.length == 9, "Your regex <code>myRegex</code> should match 9 items.");'
  - text: Your regex <code>myRegex</code> should use the global flag.
    testString: 'assert(myRegex.flags.match(/g/).length == 1, "Your regex <code>myRegex</code> should use the global flag.");'
  - text: Your regex <code>myRegex</code> should use the case insensitive flag.
    testString: 'assert(myRegex.flags.match(/i/).length == 1, "Your regex <code>myRegex</code> should use the case insensitive flag.");'
