Sure, if you want speed use `Enum`.  
But I do not think my solution would be slower, because of the `Enum.at`.  
But memory usage will be bad with my solution.

This will be way better:

```elixir
defp reverse2([], result), do: result
defp reverse2([word | rest], result) do
  reverse2(rest, [word | result])
end

```
