🚀 Why is Git INSANELY Fast? (And How Commits Actually Work)

Graphite Stack Diff → https://graphite.plug.dev/iYyiiR5 In this video, we slow down git commit and trace exactly what Git does under the hood, from your keystroke to the stored commit object. You’ll learn: • How Git stores files as blobs • What the staging area really contains • How trees represent directory structure • How commit objects are created • Why branches are just pointers • How Git achieves deduplication • Why Git history is immutable • How the reflog saves you from mistakes By the end, you’ll understand why Git’s design is both simple and brilliant. This is essential knowledge for software engineers, system designers, and anyone who works with Git daily.
