But note that it's a normal Git practice to crunch a series of small
commits which introduce partial changes (and comprise non-working
states of a program) on a private feature branch, and then
"squash-merge" [*] them into a single pretty commit on an integration
branch which is to be published (i.e. pushed somewhere).  You don't
*have to* take this route but some people prefer to do things this
way.  One upside of this approach is relative ease of rolling back to
any committed state while you're exploring possible ways to implement a
feature by trial and error.

[*] Read up on the "--squash" option of the `git merge` command.
