Exercises — Stage 9: Edit, Commit, Push Again

Exercise 1: Run the loop again

Goal: Feel how quick the loop becomes once you know it.

Steps:

1. Change the tagline in index.html from "Press Start to begin your adventure." to "Press Start. Dodge the boxes.".
2. git add index.html.
3. git commit -m "Updated tagline".
4. git push.
5. Refresh GitHub.

What happened: One short loop. No new commands. This is everyday Git.

Exercise 2: Commit multiple small changes in a row

Goal: Practice making many small commits.

Steps:

1. Change the High Score value to 250. Commit and push.
2. Change the Lives to 5. Commit and push.
3. Run git log --oneline — you see each change as a separate save point.

What happened: Small, focused commits are good. Each commit describes one change. Future you can revert any single step without losing the others.

Exercise 3: Edit directly on GitHub

Goal: See that GitHub can also commit for you.

Steps:

1. On github.com, open index.html in your repo.
2. Click the pencil icon (edit).
3. Change the <h1> text.
4. Scroll down, write a commit message, click Commit changes.
5. Back in your terminal, run git pull. Your local repo updates.

What happened: GitHub's web editor makes its own commit on your remote main. git pull fetches remote commits and merges them into your local branch. Edits can go either way — local-then-push, or remote-then-pull.

Exercise 4: Look at the reflog

Goal: See Git's internal log of everything you did.

Steps:

1. Run git reflog.

What happened: Every commit, checkout, reset, and merge you did is logged here. The reflog is your safety net — even if you accidentally delete something, you can usually find it in git reflog and recover.
