How do you delete a branch locally and remotely?

Short answer: Locally: git branch -d feature/old-branch (-D for force delete if it’s not merged) Remotely: git push origin --delete feature/old-branch Real-world example: After merging your feature branch into main, you can safely delete it to keep your repository clean.
