The revert command in Git is designed to undo changes by creating a new commit that counteracts the effects of a previous commit. When you execute a revert, Git identifies the specified commit and generates a new commit that reverses the changes made by that commit. This means that the history of changes is preserved, allowing you to maintain a clear and audit-able sequence of actions taken in the repository.

This approach is particularly useful because it does not alter the project's history, unlike other methods such as reset, which can rewrite commit history and potentially lead to loss of important changes if not handled carefully. The revert command ensures that the original commit remains part of the history, making it possible to roll back changes while keeping a record of what was done.

In summary, the revert command effectively allows developers to negate changes without disrupting the integrity of the commit history, making it an essential tool in collaborative development environments.
