What Is Git and GitHub? A Beginner’s Guide for Developers

If you're starting your journey in web development or software engineering, you've probably heard about Git and GitHub. Although they are often mentioned together, they serve different purposes.

In this beginner-friendly guide, you'll learn what Git and GitHub are, why they're important, and how they can improve your development workflow.

What Is Git?

Git is a distributed version control system that helps developers track changes in their code over time. It allows you to save different versions of your project, revert to previous versions if something goes wrong, and collaborate with others without overwriting each other's work.

Benefits of Git

Tracks every code change.
Easily restore previous versions.
Create separate branches for new features.
Collaborate with multiple developers.
Keeps project history organized.

What Is GitHub?

GitHub is a cloud-based platform that hosts Git repositories online. It allows developers to store, manage, and share their projects with others.

GitHub also provides tools for:

Team collaboration
Code reviews
Issue tracking
Project management
Continuous Integration (CI/CD)
