Transformation: Take First n Items

Our next transformation is to extract the first count entries from the list. Resisting the temptation to write the function ourselves,^[25] we discover the built-in Enum.take:

  def process({user, project, count}) do
    Issues.GithubIssues.fetch(user, project)
    |> decode_response
    |> convert_to_list_of_maps
    |> sort_into_ascending_order
    |> Enum.take(count)
  end
