## Description
<section id='description'>
You've learned that you can use a shortcut to match alphanumerics <code>[A-Za-z0-9_]</code> using <code>\w</code>. A natural pattern you might want to search for is the opposite of alphanumerics.
You can search for the opposite of the <code>\w</code> with <code>\W</code>. Note, the opposite pattern uses a capital letter. This shortcut is the same as <code>[^A-Za-z0-9_]</code>.

```js
let shortHand = /\W/;
let numbers = "42%";
let sentence = "Coding!";
numbers.match(shortHand); // Returns ["%"]
sentence.match(shortHand); // Returns ["!"]
```

## Instructions
<section id='instructions'>
Use the shorthand character class <code>\W</code> to count the number of non-alphanumeric characters in various quotes and strings.

## Tests

```yml
tests:
  - text: Your regex should use the global flag.
    testString: assert(nonAlphabetRegex.global);
  - text: Your regex should find 6 non-alphanumeric characters in <code>"The five boxing wizards jump quickly."</code>.
    testString: assert("The five boxing wizards jump quickly.".match(nonAlphabetRegex).length == 6);
  - text: Your regex should use the shorthand character to match characters which are non-alphanumeric.
    testString: assert(/\\W/.test(nonAlphabetRegex.source));
  - text: Your regex should find 8 non-alphanumeric characters in <code>"Pack my box with five dozen liquor jugs."</code>
    testString: assert("Pack my box with five dozen liquor jugs.".match(nonAlphabetRegex).length == 8);
  - text: Your regex should find 6 non-alphanumeric characters in <code>"How vexingly quick daft zebras jump!"</code>
    testString: assert("How vexingly quick daft zebras jump!".match(nonAlphabetRegex).length == 6);
  - text: Your regex should find 12 non-alphanumeric characters in <code>"123 456 7890 ABC def GHI jkl MNO pqr STU vwx YZ."</code>
    testString: assert("123 456 7890 ABC def GHI jkl MNO pqr STU vwx YZ.".match(nonAlphabetRegex).length == 12);
