Move any general JavaScript functions out into their own files so that they can be testable.

Being testable entails:

Passing in arguments to the functions as opposed to relying on external variables
Returning a value from the function, as opposed to modifying an external variable
Essentially, data in, data out

Make the functions 'pure functions'.
