## Description
|
|
<section id='description'>
|
|
In the last challenge, you searched for the word <code>"Hello"</code> using the regular expression <code>/Hello/</code>. That regex searched for a literal match of the string <code>"Hello"</code>. Here's another example searching for a literal match of the string <code>"Kevin"</code>:
|
|
<blockquote>let testStr = "Hello, my name is Kevin.";<br>let testRegex = /Kevin/;<br>testRegex.test(testStr);<br>// Returns true</blockquote>
|
|
Any other forms of <code>"Kevin"</code> will not match. For example, the regex <code>/Kevin/</code> will not match <code>"kevin"</code> or <code>"KEVIN"</code>.
|
|
<blockquote>let wrongRegex = /kevin/;<br>wrongRegex.test(testStr);<br>// Returns false</blockquote>
|
|
A future challenge will show how to match those other forms as well.
