I'm working on a small project, and I am using Github as version control. I made a new branch to test something out, and have decided I liked the previous method better (in the master branch).
What is the intended paradigm for branches in git? Do they denote that a different attempt was made, and it was not used (if the branch was not merged), or would it imply that more work is being done in that direction?
My more practical question is: Should I just delete the branch, or can I just leave it there (as I'd like to leave the "test" code there, in case I need it later)?
