We can split a string by a delimiting string in Ruby using String#split.
Ruby uses this same method to perform regular expression based splits. See
preg_match for examples.
{{code:php $result = explode("; ", "derek@example.com; mike@example.com"); var_export($result); // => array(0 => 'derek@example.com', 1 => 'mike@example.com') }}
{{code:ruby p "derek@example.com; mike@example.com".split("; ") # => ["derek@example.com", "mike@example.com"] }}
