git-checkoutgit-checkout, the Swiss army knife™ of git, has various pieces of
functionality built in. Two I've picked up over the years have since been moved
into other functions, which has made git-checkout obsolete for me and reduced
autopilot induced git-checkout anxiety:
Switching branches:
# instead of `git checkout master`:
$ git switch branch-name
# to create and switch to a new branch
$ git switch -c new-branch-name
Resetting files back to state at last commit:
# instead of `git checkout -- .`
$ git restore .
Gone is the fear of accidentally destroying all of your uncommitted changes when switching branches.
