Constructor functions begin w capital letter and should be preceded by 'new'. Use some_var = new SomeFunction(); to create objects inheriting from SomeFunction.
An object in JS is a dynamic collection of properties.The three basic operations on an object are 'get' (object.name), 'set' (object.name = some_value;), and 'delete' (delete object.name).
JS has prototypes, not classes. Make an object and then create objects that inherit from that object with 'object.create'.
Everything in js except null and undefined is an object.
Objects are passed by reference in js.
