## Match Whitespace
This is a stub. <a href='https://github.com/freecodecamp/guides/tree/master/src/pages/certifications/javascript-algorithms-and-data-structures/regular-expressions/match-whitespace/index.md' target='_blank' rel='nofollow'>Help our community expand it</a>.
### Problem:
<a href='https://github.com/freecodecamp/guides/blob/master/README.md' target='_blank' rel='nofollow'>This quick style guide will help ensure your pull request gets accepted</a>.
We need to change the regex ```countWhiteSpace``` to look for multiple whitespace characters in a string.
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
### Solution:
```js
let sample = "Whitespace is important in separating words";
let countWhiteSpace = /\s/g; // Change this line
let result = sample.match(countWhiteSpace);
```
