This facilitates the feature branch workflow popular with many Git users. Feature branches provide an isolated environment for every change to your codebase.

How does a Git work?

Git finds that commit object by its hash, then it gets the tree hash from the commit object. Git then recurses down the tree object, uncompressing file objects as it goes. Your working directory now represents the state of that branch as it is stored in the repo.
