Git is the most important tool in software development. You can think of Git as a superpower that gives you the ability to create multiple versions of your code, easily collaborate with others, and rollback changes with a simple command. I remember the first time I used Git—everything changed.
What is Git and Why It Matters
Git is a distributed version control system that lets you track changes in your code over time. Unlike centralized version control like SVN, where you depend on one main server, Git works across multiple computers—so you can code anywhere and still track your progress. It tracks every file change, including deletions and renames, so you'll never lose a version of your code.
