git

Git is a way to keep track of your code. It's like a journal for your code so that you can look back and see what you have changed and when you did it. It's like a way to store every version of your code and make sure you don't lose any of it. When you work on something, you can save your work and then come back later to make changes. When you do, git stores the older version and the new version so you can always go back and look at how something was before. You can also share your code with others using git so they can use and edit people's code.
