Blobs, Trees & Commits: The 3 Objects That Power Git (Finally Explained)
Every git commit stores 3 hidden objects. Most developers run `git commit` daily without knowing what Git actually created.
This video changes that — no memorization, no command lists. Just a clear, first-principles look at how Git stores your code and why it works the way it does.
📌 What you'll learn:
→ What a blob is and how Git hashes your file content
→ How tree objects capture a full snapshot of your directory
→ How do commit objects link everything into a permanent timeline
→ Why understanding these 3 objects makes every Git command finally click
