Git Basics for Beginners: Push, Pull, and Track Code Changes
Git is a version control tool that helps developers track changes in their code and collaborate safely. Instead of creating multiple versions of the same file, Git records what changed, when it changed, and who made the change. This makes it easy to work in teams and recover from mistakes.
Git works in a project folder called a repository. You work locally on your computer, then sync your changes to a remote repository such as GitHub.
Creating a Git Repository
Start tracking a new project:
git init
Copy an existing project:
git clone https://github.com/username/project.git
Tracking Changes
Check the current state of your project:
git status
Stage a specific file:
git add filename.js
Stage all changes:
git add .
Save a checkpoint:
git commit -m "Add login validation"
Pushing and Pulling Code
Send your commits to the remote repository:
git push
First-time push:
git push -u origin main
Get the latest updates from the remote repository:
git pull
Always pull before starting work to avoid conflicts.
A Typical Daily Git Workflow
git pull
write code
git status
git add .
git commit -m "Fix payment validation bug"
git push
Viewing History and Changes
View commit history:
git log
See what changed in files:
git diff
Common Beginner Mistakes
Forgetting to pull before working, writing unclear commit messages, committing broken code, or being afraid to make mistakes. Git is designed to recover from errors safely.
Final Thoughts
Git is simply about tracking changes, saving checkpoints, and syncing work with others. Learn these core commands first: git status, git add, git commit, git push, and git pull. Everything else builds on them.
