Git 3-Way Merge Explained | Fast Forward vs Divergence with git log --graph + MCQs
In this Git tutorial, you’ll learn exactly when branch divergence happens and why Git sometimes performs a Fast-Forward merge and other times requires a 3-Way Merge.
Using a complete hands-on lab, I explain Git branching, commit history, git log --graph visualization, merge commits, common ancestors, and Git internals step-by-step.
🚀 In this lesson, you will learn:
✅ What branch divergence really means in Git
✅ When Fast-Forward merge is possible
✅ Why Git requires a 3-Way Merge
✅ How Git identifies the common ancestor commit
✅ How to read git log --oneline --graph correctly
✅ Meaning of *, |, /, and merge graph structures
✅ How Git creates merge commits internally
✅ How to inspect commit parents using git cat-file
✅ Why deleting a branch does NOT delete commits
