The way we write phone numbers is a good example of a simple external DSL that is easy to parse with regular expressions. We don’t often consider phone numbers as a domain specific language but we do assign particular meaning to each part. The phone number representation has a particular structure which helps us better understand it as a whole. Let’s take an example number written like this: (212) 555-1234 create a regular expression to match this number in ruby
