Welcome to Day 3 of our GitHub series! Today we're diving into branching and merging—the secret sauce behind collaborative development. If GitHub was a movie, branches would be the plot twists, and merges would be the dramatic reunions. Let's get into it!
? What is a Branch?
A branch in Git is like a sandbox where you can work on changes without affecting the main (production) version of your code.
Imagine you're writing a novel. Your main branch is the final version, but you want to try out an alternate ending. Instead of rewriting everything, you create a branch called alternate-ending and work there. Genius, right?
? Creating a Branch
git branch feature-cool-button
? Switching to Your Branch
git checkout feature-cool-button
OR
git switch feature-cool-button
Now you're in your own bubble. Make changes, commit them, and live your best dev life.
Merging: The Reunion Episode
Once you’re happy with your changes in a branch, it’s time to bring them back into the main branch. That’s merging.
? First, Switch to Main
git checkout main
? Merge Your Branch
git merge feature-cool-button
Boom! Your changes are now part of the main storyline.
What About Merge Conflicts?
Sometimes Git gets confused if the same part of a file has been changed in both branches. It’ll raise a merge conflict and ask you to resolve it.
Don't panic.
git add conflicted-file.js
git commit
? Pro Tips
If you're working with a team or contributing to open source, don’t just merge directly. Open a pull request on GitHub.
Why?
Branching and merging are powerful tools for working independently without chaos. Master these, and you’re halfway to becoming a Git wizard.
Coming Up: Day 4 - GitHub Actions
Next, we’ll explore how to automate workflows and save time with GitHub Actions. Get ready for some dev magic!

What About Merge Conflicts?Sometimes Git gets confused if the same part of a file has been changed in both branches. It’ll raise a merge conflict and ask you to resolve it.
Don't panic.
- Git will mark the conflicts in the file.
- You decide which version to keep.
- After editing, mark the conflict as resolved:
git add conflicted-file.js
git commit
? Pro Tips
- Name your branches clearly: bugfix-login-issue, feature-dark-mode.
- Always pull latest changes before you merge.
- Use git log --graph to visualize branches.
- Use git status to stay aware of what’s going on.
If you're working with a team or contributing to open source, don’t just merge directly. Open a pull request on GitHub.
Why?
- It allows others to review your code.
- You can discuss changes before merging.
- Ensures cleaner, safer code.
