Question

I have the following function:

def price
  if super == nil
    return 'super'
  end
  super
end

nil is being returned. How is this possible? Should the if statement catch super if it equals nil and then return ‘super’

Answer 1

If super can return different values each time, this is possible (if unlikely). Perhaps try the following? It only calls super once, so it doesn’t have that pitfall.

def price
  super || 'super'
end
