What is a Fast-Forward Merge in Git?
❓ Interview Prompt: Explain Fast-Forward merges vs non-fast-forward merges (--no-ff) and preserving explicit merge commit nodes.
A Fast-Forward Merge occurs when merging a feature branch into a target branch where the target branch has received no intermediate commits. Git simply advances the target branch pointer forward. Running git merge --no-ff forces an explicit merge commit.
Code Implementation Example
bash
git merge feature/login
git merge --no-ff feature/login -m "merge: integrate feature/login"💡Executing default fast-forward merge vs forced explicit merge commit.
🎯 Interview Key Takeaway
Fast-forward merges move branch pointers without merge commits. Use --no-ff to force explicit merge commit history.
