Workshop Details

• The goal of this exercise is to take a working solution and refactor it until there is as little repetition as possible.
• Here are the steps of the workshop:
  • Run guard (Guard should be running at all times during the exercise)
    • See above for instructions.
  • Open the bottles.rb file:
    • Choose two chunks of the code that are the most similar.
    • Refactor the code to remove the smallest difference between these two chunks.
      • If your changes cause tests to fail, undo the changes until the tests are passing again and retry.
    • Repeat with the next part of the code that is the most similar.
    • Continue until there is the least amount of repetition in your solution.
