Git Worktrees Let You Handle Interruptions Without Stashing Your Work

Git has supported a feature called 'git worktree' since version 2.5, allowing developers to create a second working directory that shares the same repository database without cloning it. When interrupted mid-feature, a developer can run 'git worktree add' to check out a separate branch in a new folder, leaving the original work completely untouched. The hotfix can be made, committed, and pushed from that second directory, after which the developer returns to find their uncommitted changes exactly as they left them. Git enforces a safety rule preventing the same branch from being checked out in two worktrees simultaneously, avoiding race conditions on branch pointers. Once the hotfix is merged, the extra directory can be cleanly removed with 'git worktree remove', while the branch itself is preserved.
