The BIG THREE - checkout vs reset vs revert — three commands that seem to "undo" things, but do completely different operations. In this video, you'll learn: → What checkout ACTUALLY does (hint: it just moves your viewpoint) → The three modes of reset: soft, mixed, and hard — and when to use each → Why hard reset can permanently destroy uncommitted work → When to use revert instead of reset (the answer: shared history) KEY INSIGHT: Checkout moves HEAD. Reset moves the BRANCH. Revert moves nothing—it creates a NEW commit. CONCEPTS COVERED: • git checkout — moving your viewpoint safely • git reset --soft — undo commits, keep changes staged • git reset --mixed — undo commits, unstage changes • git reset --hard — nuclear option, destroys uncommitted work • git revert — safe undo for shared/pushed commits WHO THIS IS FOR: Developers who've used these commands but dont fully understood the difference. #git #gitreset #gitcheckout #gitrevert #gittutorial #programming #softwaredevelopment #coding #webdevelopment #github #versioncontrol #learntocode #softwareengineering #developer #devtools
