## Description
|
||
|
|
<section id='description'>
|
||
|
|
Sometimes whitespace characters around strings are not wanted but are there. Typical processing of strings is to remove the whitespace at the start and end of it.

## Instructions
|
||
|
|
<section id='instructions'>
|
||
|
|
Write a regex and use the appropriate string methods to remove whitespace at the beginning and end of strings.
|
||
|
|
<strong>Note</strong><br>The <code>.trim()</code> method would work here, but you'll need to complete this challenge using regular expressions.

|
||
|
|
testString: 'assert(result == "Hello, World!", "<code>result</code> should equal to <code>"Hello, World!"</code>");'
|
||
|
|
- text: You should not use the <code>.trim()</code> method.
|
||
|
|
testString: 'assert(!code.match(/\.trim\(.*?\)/), "You should not use the <code>.trim()</code> method.");'
|
||
|
|
- text: The <code>result</code> variable should not be set equal to a string.
|
||
|
|
testString: 'assert(!code.match(/result\s*=\s*".*?"/), "The <code>result</code> variable should not be set equal to a string.");'
