								In the last challenge, you searched for the word `"Hello"`  using the regular expression `/Hello/` . That regex searched for a literal match of the string `"Hello"` . Here's another example searching for a literal match of the string `"Kevin"` :

								Any other forms of `"Kevin"`  will not match. For example, the regex `/Kevin/`  will not match `"kevin"`  or `"KEVIN"` .
