What is the difference between main and master in Git ?

In Git, "main" and "master" are both commonly used as the default branch name for a repository. However, "master" has historically been the default branch name in Git, while "main" is a more recent alternative that has gained popularity due to concerns about the term "master" being associated with slavery and racism. Functionally, there is no difference between "main" and "master" in Git, and you can use either one as the default branch name for your repository.
