# --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 <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.
|
|
|
|
# --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.
|
|
|
|
# --hints--
|
|
|
|
Your regex `myRegex` should match 9 items.
|
|
|
|
```js
|
|
assert(result.length == 9);
|
|
```
|
|
|
|
Your regex `myRegex` should use the global flag.
|
|
|
|
```js
|
|
assert(myRegex.flags.match(/g/).length == 1);
|
|
```
|
|
|
|
Your regex `myRegex` should use the case insensitive flag.
|
|
|
|
```js
|
|
assert(myRegex.flags.match(/i/).length == 1);
|
|
```

|

```js
|
|
let quoteSample = "3 blind mice.";
|
|
let myRegex = /[^0-9aeiou]/gi; // Change this line
|
|
let result = quoteSample.match(myRegex); // Change this line
|
|
```
