2. JavaScript Class..Object (Limited, class..new)

Creating classes in JavaScript is not really OOP, but rather a super type. That is, a type that has some class-like features but is missing the necessary OOP requirements.

There is nothing in Javascript to stop you from accessing the functions within your class outside of the class so this is not fully OOP but is usable.

3. JavaScript Custom Routines (function)

JavaScript uses functions and loosely typed parameters. Function definitions must come before their usage so the usual preference when adding JavaScript to HTML pages is to include them between the head tags.
