# --description--
|
||
|
|
|
||
|
|
Up until now, you've looked at regexes to do literal matches of strings. But sometimes, you might want to also match case differences.
|
||
|
|
|
||
|
|
Case (or sometimes letter case) is the difference between uppercase letters and lowercase letters. Examples of uppercase are `A`, `B`, and `C`. Examples of lowercase are `a`, `b`, and `c`.
|
||
|
|
|
||
|
|
You can match both cases using what is called a flag. There are other flags but here you'll focus on the flag that ignores case - the `i` flag. You can use it by appending it to the regex. An example of using this flag is `/ignorecase/i`. This regex can match the strings `ignorecase`, `igNoreCase`, and `IgnoreCase`.

# --instructions--

Write a regex `fccRegex` to match `freeCodeCamp`, no matter its case. Your regex should not match any abbreviations or variations with spaces.
