Your commit is fine except for the "first" vs "third". The full explanation for `process.argv` is already [here](https://github.com/rvagg/learnyounode/blob/77e9a50b08b9c9a5d52779eb128b124605a3fb33/problems/baby_steps/problem.txt#L7-L28) in BABY STEPS so this just needs to be a reminder and the bit in brackets is good.

Just change "third" back to "first" and I'll merge your changes.

Thanks for contributing!
