## Description
|
||
|
|
<section id='description'>
|
||
|
|
Sometimes we want to check for groups of characters using a Regular Expression and to achieve that we use parentheses <code>()</code>.
|
||
|
|
If you want to find either <code>Penguin</code> or <code>Pumpkin</code> in a string, you can use the following Regular Expression: <code>/P(engu|umpk)in/g</code>
|
||
|
|
Then check whether the desired string groups are in the test string by using the <code>test()</code> method.
|
||
|
|
<blockquote>let testStr = "Pumpkin";<br>let testRegex = /P(engu|umpk)in/g;<br>testRegex.test(testStr);<br>// Returns true</blockquote>

## Instructions
|
||
|
|
<section id='instructions'>
|
||
|
|
Fix the regex so that it checks for the names of <code>Franklin Roosevelt</code> or <code>Eleanor Roosevelt</code> in a case sensitive manner and it should make concessions for middle names.
|
||
|
|
Then fix the code so that the regex that you have created is checked against <code>myString</code> and either <code>true</code> or <code>false</code> is returned depending on whether the regex matches.

|
||
|
|
testString: assert(myRegex.test('Eleanor Roosevelt'), 'Your regex <code>myRegex</code> should return <code>true</code> for the string <code>Eleanor Roosevelt</code>');
|
||

|
- text: Your regex <code>myRegex</code> should return <code>false</code> for the string <code>Franklin Rosevelt</code>
|
||
|
|
testString: assert(!myRegex.test('Franklin Rosevelt'), 'Your regex <code>myRegex</code> should return <code>false</code> for the string <code>Franklin Rosevelt</code>');
|
||
|
|
- text: You should use <code>.test()</code> to test the regex.
|
||
|
|
testString: assert(code.match(/myRegex.test\(\s*myString\s*\)/), 'You should use <code>.test()</code> to test the regex.');
|
||
|
|
- text: Your result should return <code>true</code>.
|
||
|
|
testString: assert(result === true, 'Your result should return <code>true</code>.');
