 Regular expressions are strings which can be used to find patterns (or lack thereof) in data. Any string can be converted to a regular expression using the `.r` method.

 In the above example, the `numberPattern` is a `Regex`
 (regular expression) which we use to make sure a password contains a number.
 
 You can also search for groups of regular expressions using parentheses.

 Here we parse out the keys and values of a String. Each match has a group of sub-matches. Here is the output:

 Moreover, regular expressions can be used as patterns (in `match` expressions) to conveniently extract the matched groups:
