In this video, I compress six “advanced Git” concepts into a quick, visual mental model so you stop panic-running random commands from Stack Overflow and actually understand what Git is doing. I start with Git refs (references): they’re basically aliases/pointers to commits, and under the hood your branches are just refs pointing at the latest commit on that branch. I also demystify HEAD—the special pointer that represents where you currently are in the repo. When HEAD points to a ref, you’re on a real branch; when it points to a “naked commit,” you’re in detached HEAD land, where new commits won’t belong to a branch unless you handle it properly. Then I move into practical workflow tools: git stash for when you accidentally start coding on the wrong branch and need to switch context without committing. After that, I break down git reset in all three modes (soft, mixed, hard) using the working tree → staging area → commit flow, so you can see exactly what gets undone and what stays. I also clarify reset vs revert: reset rewrites history (dangerous if pushed), while revert creates a new commit that undoes changes (safer for shared repos). Finally, I cover git reflog—your “journal” of where HEAD has been—so you can recover from mistakes like a hard reset by finding the commit you lost and moving back to it.
