| ## Description
 | |
| <section id='description'>
 | |
| So far, you have only been checking if a pattern exists or not within a string. You can also extract the actual matches you found with the <code>.match()</code> method.
 | |
| To use the <code>.match()</code> method, apply the method on a string and pass in the regex inside the parentheses. Here's an example:
 | |
| <blockquote>"Hello, World!".match(/Hello/);<br>// Returns ["Hello"]<br>let ourStr = "Regular expressions";<br>let ourRegex = /expressions/;<br>ourStr.match(ourRegex);<br>// Returns ["expressions"]</blockquote>
