Yes I have sometimes wondered about that. In fact another aspect of npm which I don't get is if you have multiple "instances" of a library (e.g. different versions, or even two copies of the same version) then any library global variables will not be shared across those instances.

But I don't know enough about JS development to say whether this really happens and/or if it is an issue (some pretty cool stuff has been done with JS so I guess it's possible to live with it).

BTW I share your dislike of hipsters, though I am a bit jealous those moustaches are just so cool.
