Your problem appears to be solved, so eventually you should know that there 
are no classes.  So there are no class objects, class variables, or member 
functions in these programming languages.  They use prototype-based, not 
class-based, inheritance.  There are constructors, constructor properties 
(properties of constructors), and prototype methods (methods of prototype 
objects).

See?  No classes, but prototype objects (here: referred by 
`ratings.prototype') attached to constructors (here: referred by `ratings') 
instead, from which other objects inherit.

Because `ratings' refers to a constructor, the identifier should be 
`Ratings' instead.
