What is Git made of? (2022)
The article explains the fundamental components of Git, a popular version control system. It details how Git stores data in a hidden directory called .git, which contains various objects such as blobs, trees, and commits. Additionally, it discusses the use of SHA hashes for uniquely identifying objects within a repository.
- ▪Git stores all its internal data in a hidden directory called .git.
- ▪Every source file committed to Git becomes a blob object, while commits and tags are also stored as objects.
- ▪Git uses SHA hashes to uniquely identify objects, with recent versions switching from SHA-1 to SHA-256 to reduce hash collisions.
Lobsters files mainly under programming. We currently carry 187 of its stories.

What is Git made of?Git can be confusing. Git can be scary. Git CLI may be the least intuitive tool you have to use on a daily basis.But also Git is a wonderfully simple and cleverly designed version control system that definitely deserves its popularity.To prove this point I invite you to implement your own tiny Git that would be able to create a local repository, commit a single file to it, view commit logs and checkout a certain revision of that file.It won’t be more than a couple hundred lines of code, we’ll try to keep things as simple as we can.
