The anatomy of Git – A beginner-friendly explanation of how Git works

Git is incredibly powerful, especially as projects become more complex. Up until now, our focus was on a straightforward history. However, where Git really shines is in its ability to handle large projects with a large number of contributors and manage the dynamically evolving code within a team seamlessly. We have come this far intuitively, working with Git operations as commands work. It is time to get down to the nitty-gritty. While it is helpful to have an intuitive feel for Git, by understanding how Git operates behind the scenes, we can harness its full potential.
