Git is a distributed version control system (VCS) that allows developers to track changes in their codebase over time. It’s an essential tool for modern software development, enabling collaboration, version tracking, and easy code management. Whether you're working on a personal project or collaborating with a team, Git is invaluable.

Module 1: What is Git and Why Should You Use It?

What is Git?

Git is a free and open-source version control system that tracks changes in files. It allows multiple developers to collaborate on the same project without overwriting each other’s work. Git records changes to files over time and allows you to revert back to earlier versions, merge code from different developers, and track what’s been done to your project.

Why Use Git?

Here are some key reasons why Git is so popular:

• Version Tracking: Git tracks every change made to your codebase, so you can view the history of changes and undo mistakes.
• Collaboration: Git enables multiple people to work on the same codebase, and it helps to avoid conflicts between different developers' changes.
• Branching and Merging: Git allows developers to work on different branches of a project. These branches can be merged back together when they’re ready.
• Backup and Safety: You can push your code to remote repositories (like GitHub or GitLab) for secure backups.
