How do different versions of the same package interact with npm? Since JS is a dynamic language, it seems that there could be problems if a function in one version of a package returned a value which was then fed to a function in a different version.

You typically import it like:

   var foo = require('foo');

The lib's functions are accessed solely via the foo object. There is no interaction when different libs require different versions of a lib because the access the lib via different objects/modules. This actually is the one aspect of javascript I wish other languages would copy.
