🔧 Git & GitHub Basics – Part 2
Learn how to use branches, check history, and work with GitHub easily!

🌿 4. Branches: Manage Your Work

git branch new-branch -> Make a new branch
git checkout branch-name -> Switch to that branch
git checkout main -> Go back to the main branch
git merge branch-name -> Bring changes from one branch into another
git branch -d branch-name -> Delete a branch
git branch -m new-name ->Rename your current branch

👉Tip: Use branches to try new ideas without breaking your main code!

📜5. See Your Commit History

git log -> See all past commits
git log --author="name" -> Commits by a person
git log -- filename -> History for one file
git log -u -> See what changed in each commit
git log --stat -> Summary of changes
git log --patch -> Detailed file changes

👉Great for tracking your work or fixing bugs.

🌐6. Pull & Push: Sync with GitHub

🔽 Pull (download updates):

cd your-folder  
git pull

🔼 Push (upload your changes):

git add .  
git commit -m "your message"  
git push

👉 Tip: Always pull before pushing to avoid conflicts.

⚡️7. Quick Git Commands (Aliases)
Make commands shorter! For example:

git config --global alias.co "checkout"

Now, use git co instead of git checkout 😎

⚡️ Quick Fixes: Debugging Common Coding Errors
Debugging is a crucial skill every coder needs to master. Here are some quick fixes for the most common coding errors that slow down your progress:

1. Syntax Errors
- Usually caused by typos, missing brackets, or incorrect punctuation.
- Fix: Carefully check your code for missing ;, }, ), or misspelled keywords.

2. Null or Undefined Errors
- Occur when you try to access a variable or object property that hasn’t been initialized.
- Fix: Use conditional checks like if (variable) or default values with ||.

3. Type Errors
- Trying to perform operations on incompatible data types (e.g., adding a number to a string).
- Fix: Use type conversions like parseInt(), toString(), or ensure variables hold the expected types.

4. Infinite Loops
- Happens when the loop’s exit condition is never met.
- Fix: Double-check your loop conditions and update statements to guarantee termination.

5. Off-by-One Errors
- Common in loops, where the iteration goes one step too far or not far enough.
- Fix: Carefully verify loop boundaries (< vs <=).

🔧 Pro Debugging Tips:

- Use debugging tools and breakpoints in your IDE.
- Add print/log statements to track variable values.
- Simplify the problem by isolating the buggy code.
