What is the purpose of a Git Push?

The primary purpose of a Git Push is to send local changes from your branch to a remote repository, thereby updating that remote repository with the latest commits you have made locally. When you push, you synchronize your local branch with the corresponding branch in the remote repository. This allows other collaborators to see the changes you've made and incorporate them into their own work.

In contrast, merging branches is a different operation, where you integrate changes from one branch into another. Undoing the last commit refers to reverting changes made in the most recent commit, which does not involve pushing changes to a remote repository. Creating a new tag is related to marking specific points in the repository's history but does not involve sending any changes to a remote location.

Overall, Git Push is vital for collaboration in a distributed version control environment, ensuring that all team members have access to the most up-to-date codebase.
