The complete list of git object types is here:
Git blob object
The git “blob” type is just a bunch of bytes that could be anything, like a text file, source code, or a picture, etc.
Learn more about the git blob object.
Git tree object
A git tree is like a filesystem directory. A git tree can point to, or include:
- Git “blob” objects (similar to a filesystem directory includes filesystem files).
- Other git trees (similar to a filesystem directory can have subdirectories).

Git commit object
A git commit object includes:
- Information about who committed (made) the change/check-in/commit. For example, it stores the name and email address.
- A pointer to the git tree object that represents the git repository when the commit was done
- The parent commit to this commit (so we can easily find out the situation at the previous commit).

Git tag object
A git tag object points to any git commit object. A git tag can be used to refer to a specific tree, rather than having to
remember or use the hash of the tree.
