This has nothing to do with Node. The disparity in patterns you're seeing
is in language experience. "bean1.js" and "bean3.js" are just explicitly
doing what "bean2.js" does for implicitly: allocate an instance object.
"bean4.js" is not a comparable pattern to 1, 2 and 3 in the initialization
sense: it's an instance of the built-in Object whose properties are being
used to expose multiple "exports", whereas 1, 2, 3 use a function to export
a single function object "export".
