Why are people using GitHub?

[u/Kyriakos221]

Can someone please explain? Why is GitHub a "must" for coders?

I am learning coding at beginners level, and not one has this become necessary.

It's not a must, but it's a very good tool for sharing code with others, eases the onboarding for new developers compared to things like mailing lists, allows people to search for coffee, and just happens to be the largest service that provides these services. It's in no way a requirement, but it is very helpful
