Git, wie man sich nicht verpflichten, sondern Veränderungen beibehält
You can use git stash, which will save your changes without creating a commit.1
First, stash your changes:
$ git stash
Then switch to your other branch:
$ git checkout branch-B
When you're ready, go back to your original branch and unstash your changes:
$ git checkout branch-A
$ git stash pop
See the documentation linked above for more details and specifics on additional use cases.
