Shameless

It's not a good idea to do work in the initializer. This should just be for assigning the input arguments to instance variables.

What you can do with this is create a private method like so:

```ruby
class Bowling
  def initialize(frames_array)
    @frames_array = frames_array
  end

  private

  attr_reader :frames_array

  def frames
    @frames ||= create_frames(frames_array)
  end
end
```
