Save As for Text: Git Without Fear

Your quote calculator has worked for three weeks. On Thursday a customer's total comes out forty dollars high, and you open the folder to go back. It holds quote-v2.html through quote-v9.html and one named quote-final-new.html.

By the end of this lesson

  • You save a numbered copy with a one line message each time the app works.
  • You go back to your last good version by reading your own log.
  • You explain why an AI tool's undo doesn't replace your saved versions.
