Git reset FAQ
- What is the difference between reset and revert?
- Reset moves your branch pointer backward; revert adds a new commit that undoes a past change — safer on shared branches.
- What does git reset --hard do?
- It moves the branch to an earlier commit and discards staged and working changes to match that commit.
- When should I use git commit --amend?
- Use amend to fix the latest commit before you push — for typos in the message or forgotten staged files.
- Can I practice reset without breaking a real repo?
- Yes. The Game4Git playground lets you experiment and see the graph update instantly.
