What is the Difference Between Git Reset and Git Revert?
The git commands reset and revert share the same purpose: to rollback commits of a git repository to a previous state. But they perform these rollbacks in a fundamentally different way.
When you use git reset, the head of the repository points back to a previous commit. So, if you made four commits to a repository and want to remove the last one, you execute git reset while specifying the third commit. This is a destructive rollback, which means that the fourth commit is now gone forever. For this reason, git reset is often not your best choice for making rollbacks.
As opposed to git reset, git revert performs a nondestructive rollback. It does this by reverting a previous commit but still leaving it in the repository. So, using our previous example, to revert the fourth commit we would execute git reset while specifying the fourth commit. You can also revert a range of commits if you have many to revert.
