coffeescript refactoring

Question

Is there any coffeescript specific trickery that would make this look neater:

index = (->
          if segment == 'index'
            return 0
          else if segment == 'inbox'
            return 2

          1
        )()

Answer 1

Yes, a switch expression:

index = switch segment
  when 'index' then 0
  when 'inbox' then 2
  else 1
