HEAD
HEAD is a special reference in Git that points to the current branch. It represents the latest commit on the current branch. When you make a new commit, HEAD moves forward to point to the new commit.
Hi! I'm Alex, creator of GitByBit.
And this is Gitopedia—a reference that summarizes knowledge in my Git course.
Gitopedia is designed to be a personal knowledge base. When you progress through the main Git course in VS Code, you unlock all of these topics, one by one, bit by bit. This gives you time to digest the information and gradually build the mental model of Git. Here's an example of how it works:
Learning directly in VS Code lets you practice Git exactly as you would in real life, doing real jobs, writing real code. In addition, the course has access to your actual terminal, so it can point out mistakes, suggest workarounds, etc.
The course is FREE, there are no Ads or other bullshit. There are optional premium add-ons you can purchase, mainly to support my work (regrettably, I have to eat every day), but that's totally up to you.
