# This example takes a `date_available` (imagine a product or service that is available on a certain date.)
# If it is `nil`, it prints `Never`.
# If it is available today or earlier, it prints `Now`.
# If it is available in the future, it prints the date it will be available.

require 'date'

date_available = Date.today # Available now

display = case date_available
when nil then 'Never'
when ..Date.today then 'Now'
else
date_available.to_s
end

puts display
