Although written for Processing’s Java Mode these 2 OOP articles can be easily applied to any Processing flavor:

1. [From several variables to arrays - Processing 2.x and 3.x Forum](http://forum.Processing.org/two/discussion/8082/from-several-variables-to-arrays.html)
2. [From several arrays to classes - Processing 2.x and 3.x Forum](http://forum.Processing.org/two/discussion/8081/from-several-arrays-to-classes.html)

This is how we create classes in JS btW:

> **[class - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/class)**
>
> The class declaration creates a binding of a new class to a given name.
