In which scenario would you typically use the "git rebase" command over "git merge"?
- When creating a new branch for a bug fix
- When dealing with conflicts in parallel branches
- When wanting to keep a linear history
- When working on a feature branch to incorporate upstream changes smoothly
The "git rebase" command is used to maintain a linear project history by moving, combining, or eliminating existing commits. It's typically employed to integrate upstream changes smoothly into a feature branch, resulting in a cleaner and more readable history.
Your team needs to develop a real-time chat application. Which framework would you recommend and why?
- ASP.NET SignalR
- Django Channels
- Firebase
