Imagine spending weeks building a project and then accidentally deleting important code... ๐ฑ
Or imagine working with a team of 10 developers where everyone is changing the same files simultaneously.
How do companies manage this?
๐ The answer is Version Control Systems (VCS).
Version Control helps developers track, manage, and collaborate on code efficiently.
๐ง 1. What is Version Control?
Version Control is a system that records changes made to files over time.
It allows developers to:
โ Track changes
โ Restore old versions
โ Collaborate with teams
โ Manage project history
โ Prevent accidental loss of code
Think of it as a "Save History" feature for your entire project.
๐ป 2. What is Git?
Git is the most popular Version Control System in the world.
It was created by Linus Torvalds.
Git runs locally on your computer and keeps track of every change you make.
๐ 3. What is GitHub?
GitHub is a cloud platform that hosts Git repositories online.
Think of it like:
Git : Tool to manage versions
GitHub : Platform to store repositories online
๐ง Why GitHub Matters
GitHub allows you to:
โ Store projects online
โ Collaborate with developers
โ Showcase your portfolio
โ Contribute to open source projects
โ Back up your code
Many recruiters check GitHub profiles before hiring developers.
๐ 4. What is a Repository (Repo)?
A Repository is a project folder managed by Git.
It contains:
โ Source code
โ Project files
โ Documentation
โ Version history
Example:
MyWebsite/
โโโ index.html
โโโ style.css
โโโ script.js
โโโ README.md
