What is Git and Why Version Control is Important

What is Git?

Git is a version control system that allows developers to keep track of changes made to their code over time. It saves a history of edits, makes it possible to restore earlier versions when needed, and enables multiple people to work on the same project without interfering with one another’s changes.

Importance of Version Control

  1. Tracks Changes – Keeps a clear record of what changed, who made the change, and why.
  2. Restores Previous Versions – Allows you to revert or compare older versions when issues arise.
  3. Enables Teamwork – Lets multiple people work on the same project without overwriting each other’s work.
  4. Supports Safe Experimentation – Uses branches to test features or fixes without affecting the main code.
  5. Provides Backup – Stores project history locally and on platforms like GitHub for added safety.
  6. Improves Code Quality – Encourages reviews, documentation, and accountability.

How to Push Code to GitHub

Pushing code means sending your local changes to a GitHub repository so they are saved online and shared with others.

Steps and commands:

  • Check which files were changed
git status
Enter fullscreen mode Exit fullscreen mode
  • Stage the files you want to include
git add .
Enter fullscreen mode Exit fullscreen mode
  • Save the changes with a message
git commit -m "Describe the changes made"
Enter fullscreen mode Exit fullscreen mode
  • Upload the changes to GitHub
git push origin main
Enter fullscreen mode Exit fullscreen mode

How to Pull Code from GitHub

Pulling code means downloading the latest changes from GitHub to your local computer. It ensures you are working with the most recent version of the project and helps avoid conflicts.

Steps and commands:

  • Get and merge the latest updates
git pull origin main
Enter fullscreen mode Exit fullscreen mode

How to Track Changes Using Git

Git allows you to monitor what has changed in your project at any time. Tracking changes helps you review work, identify errors, and understand how the project has evolved.

Useful commands to use

  • View the current state of your files
git status
Enter fullscreen mode Exit fullscreen mode
  • See line-by-line changes
git diff
Enter fullscreen mode Exit fullscreen mode
  • View commit history
git log
Enter fullscreen mode Exit fullscreen mode
