Discussion: build-first or component-first?

[vados-cosmonic]

While talking with Danny, the thought of whether users who enter the guide should first build a component or compose a component with already existing functionality came up.

I think it's worth discussion (with a time box probably, so we don't bike shed forever). I like the idea of building a small component (the adder we have today) before being introduced to trying to reuse functionality, but I can see the simplicity/applicability of showing people how to import functionality first as well.

Would like to open up discussion (for a few weeks at least) and see if there are any other opinions here/user feedback to gather.
