title: Match Literal Strings

## 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>:
|
|
|
|
```js
|
|
let testStr = "Hello, my name is Kevin.";
|
|
let testRegex = /Kevin/;
|
|
testRegex.test(testStr);
|
|
// Returns true
|
|
```
|
|
|
|
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>.
|
|
|
|
```js
|
|
let wrongRegex = /kevin/;
|
|
wrongRegex.test(testStr);
|
|
// Returns false
|
|
```
|
|
|
|
A future challenge will show how to match those other forms as well.
