Resetting commits is crucial for cleaning up local repository history before sharing changes, allowing you to reorganize commits and remove unwanted changes. As the creator of CoreUI, a widely used open-source UI library, I’ve used git reset extensively for local history cleanup over 25 years of development. From my expertise, the most versatile approach is using git reset with different modes depending on whether you want to preserve or discard changes. This provides precise control over how commits are undone and what happens to the affected files.
