Sometimes when we are working we need a way to pause and switch gears to deal with something more critical; often when this happens we aren't ready to create a
git commit; instead, we can use
git stash to save our uncommitted changes locally, switch branches and fix the critical issue, switch back to our incomplete feature, and finally run
git stash apply to get our unfinished changes back into our branch without affecting the rest of the codebase. In this lesson, we show a real world example of doing this with a critical bug.
