Tags work as an additional identifier for a particular incident. And in the case of Git, Tags are used as the reference points in your development workflow and it denotes special events like a new version release or new commit. You can create a new tag to give a reference for your newly launched version. We use tags for future reference of our previous releases and commits. And we can create and delete as per our convenience. To delete a tag from a local repository, We can use the “git tag -d” command followed by the tag name you want…
