What Is Learn Git Branching?

Updated

Learn Git Branching (learngitbranching.js.org) is a browser-based interactive tool for learning Git, with a focus on visualizing branches and commits. It simulates a Git repository directly in your browser, so you don't need to install Git or set up a local repository to start practicing. The only requirement noted on the site is that JavaScript must be enabled for the app to run.

What You Can Do With It

The tool is built around two connected activities:

  • Lessons that introduce Git concepts, especially branching and merging.
  • Practice challenges that ask you to reach a specific repository state using Git commands.

Because the repository is simulated in the browser, you get immediate visual feedback: as you type commands, the commit graph updates so you can see how each command changes branches, commits, and history.

Why the Visualization Matters

Git's branching model is easier to understand when you can see it. In a normal terminal, commands like git rebase or git cherry-pick change history in ways that aren't obvious from text output alone. Learn Git Branching renders the commit graph, so the effect of a command is visible right away. This makes it useful for building intuition about how branches relate to each other before you apply the same commands in a real project.

When to Use It

Learn Git Branching fits well if you:

  • Are new to Git and want to understand branching without risking a real repository.
  • Already use basic Git commands but find rebasing, cherry-picking, or resetting confusing.
  • Want to practice specific scenarios repeatedly until the commands feel natural.

It is less suited as a reference for everyday Git workflows or for learning non-branching topics in depth. Treat it as a practice environment for branching and history manipulation, not as a complete Git course.

How to Get Started

  1. Open learngitbranching.js.org in a browser with JavaScript enabled.
  2. Start with the introductory levels, which walk through commits and branches.
  3. Type Git commands into the simulated terminal and watch the graph update.
  4. Work through the challenge levels, which give you a target state to reach.

A Practical Note

The commands you practice here are the same ones you use in a real repository, so the skills transfer directly. The difference is that mistakes cost nothing — you can reset a level and try again. That makes it a low-risk way to build confidence before running branch-rewriting commands on actual work.
