Git is a free and open source distributed version control system designed to handle everything from small to massive projects with speed and efficiency.
Git literally tracks every line of code you change locally. If you break your application, you can safely revert your files back to the exact hour they worked.
Developers can create an isolated "branch" to experimentally build new features without risking destruction to the stable "main" code.
Combined with GitHub or GitLab, multiple developers can work simultaneously on the same project and elegantly cleanly merge their code together.
Git is a terminal command-line tool. You initialize it inside your project folder.
