NOTE: Why I use yarn? I was following VuePress documentation and it seems to prefer yarn, so I decide to give it a try. BTW, I am no expert or avid user of npm/yarn.

Can yarn and npm co-exist on same machine?

Yes, they seems to be independent (at the same time compatible) of each other. I don't see any conflict so far.

NOTE: I didn't try mixing yarn and npm in the same project.
