Understanding the git internals, a deep dive into the .git folder [Advanced]

Learn git the hard way! I’m re-implementing git from the ground up so that you can get the chance to understand at a very deep level how this tool works.

git is a tool that is used by millions of developers every day, but it’s also a tool that is often misunderstood. I want to help you understand how git works, and how you can use it more effectively.

In this part, I covered:

  • deep dive into the .git folder
  • understanding objects, trees, blobs, and their representation on disk
  • scaffolding the CLI and implementing git init, git commit
