## Description
|
|||
|
|
<section id="description">到目前为止，你已经看过正则表达式来进行字符串的字面匹配。但有时，您可能还希望匹配案例差异。大小写（或有时是大写字母大小写）是大写字母和小写字母之间的区别。大写的示例是<code>"A"</code> ， <code>"B"</code>和<code>"C"</code> 。小写的示例是<code>"a"</code> ， <code>"b"</code>和<code>"c"</code> 。您可以使用所谓的标志来匹配这两种情况。还有其他标志，但在这里你将专注于忽略大小写的标志 - <code>i</code>旗帜。您可以通过将其附加到正则表达式来使用它。使用此标志的示例是<code>/ignorecase/i</code> 。此正则表达式可以匹配字符串<code>"ignorecase"</code> ， <code>"igNoreCase"</code>和<code>"IgnoreCase"</code> 。 </section>

## Instructions

|
|
<section id="instructions">写一个正则表达式<code>fccRegex</code>来匹配<code>"freeCodeCamp"</code> ，无论它的情况如何。您的正则表达式不应与任何缩写或带有空格的变体匹配。 </section>
