The Refactor Factory
What You'll Be Fixing

All right! We're going to reinforce our knowledge of Ruby best practices by refactoring some existing code. As mentioned, refactoring is the process by which we improve a code's structure, appearance, and/or performance without modifying its overall behavior.

The code in the editor is a Ruby method, first_n_primes, that takes a number n and generates a list of the first n prime numbers. Unfortunately, our poor author hasn't yet mastered all the tools available in Ruby. But we can fix that!
