Great job on this assignment. A few notes:

• Make sure you keep an eye on your indentation and that your text editor is set to the style specifications for the language you are writing in. For ruby and javascript it will always be 2 spaces or 1 tab. Indentation really helps with readability and segmenting/organizing sections of your code.
• Great use of an OR statement for checking your quitting condition
