Gitlet is an implemention of Git in JavaScript.

Over the last six years, I’ve become better at using Git for version control. But my conceptions of the index, the working copy, the object graph and remotes have just grown fuzzier.

Sometimes, I can only understand something by implementing it. So, I wrote Gitlet, my own version of Git. I pored over tutorials. I read articles about internals. I tried to understand how API commands work by reading the docs, then gave up and ran hundreds of experiments on repositories and rummaged throught the .git directory to figure out the results.

I discovered that, if approached from the inside out, Git is easy to understand. It is the product of simple ideas that, when combined, produce something very deep and beautiful.
