Question

About GitHub

Answer 1

You can use an online git repo for free. In case you lose your computer, you automatically have a backup. It also enables others to use your code or contribute to it.

Answer 2

An online one probably lends itself more to greater collaboration.

Answer 3

There are a lot of advantages using online repo over local one, it's much easier to clone code and commit push the repos from any devices and work team collaboration.
Cloud deployment from docker using repo is a more convenient way.

You can set your repos as private repos if they are not intended to share as public codes.
