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 <dfn>negated character sets</dfn>.
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.
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.
Your regex myRegex should match 9 items.
assert(result.length == 9);
Your regex myRegex should use the global flag.
assert(myRegex.flags.match(/g/).length == 1);
Your regex myRegex should use the case insensitive flag.
assert(myRegex.flags.match(/i/).length == 1);
let quoteSample = "3 blind mice.";
let myRegex = /change/; // Change this line
let result = myRegex; // Change this line
let quoteSample = "3 blind mice.";
let myRegex = /[^0-9aeiou]/gi; // Change this line
let result = quoteSample.match(myRegex); // Change this line
