Best Practices

Commit Often: Make small, frequent commits to avoid large chunks of uncommitted changes.

Use Meaningful Stash Messages: When stashing, use descriptive messages to easily identify the context of your changes.

Review Before Committing: Ensure your changes are stable and ready before committing to maintain the integrity of your project history.

By using these strategies, you can efficiently manage uncommitted changes and switch branches without losing your work. Understanding and utilizing these Git commands will improve your workflow and help you handle uncommitted changes with confidence.
