? Git Introduction

? Quick Overview

Git is a powerful and widely-used version control system for managing the history of a project. It's designed to help teams of developers track changes in the code, collaborate efficiently, and keep a clean history of all changes made in a project.

? Key Concepts

Git works by recording snapshots of files over time, allowing developers to move back and forth between versions safely.

? What is Version Control?

Version control systems like Git allow developers to keep track of every modification made to a project. This makes it easy to revert to previous versions, compare changes, and collaborate without fear of overwriting each other’s work.

? Key Features of Git

• Distributed: Every developer has a full copy of the project history.
• Branching and Merging: Work on features independently and merge later.
• Fast Performance: Optimized for speed even on large projects.
• Collaboration: Multiple developers work safely together.
• History Tracking: View, compare, and restore changes.

? Syntax / Theory

1️⃣ Initializing a Repository

You can initialize a Git repository by running the following command:

// Initializes a new Git repository in the current folder
git init

2️⃣ Tracking Changes

To track changes to files, add them to the staging area:

// Adds a specific file to the staging area
git add file_name

Then commit those changes with a message:

// Saves staged changes into the repository history
git commit -m "Commit message"

? Live Output / Explanation

After committing, Git stores a snapshot of your files and assigns a unique commit ID that can be revisited anytime.

? Interactive Concept

Imagine Git as a timeline where each commit is a checkpoint. You can safely jump between checkpoints without losing work.
