Javascript and p5js Expert to Modularize Complex Codes

I have complex codes for many Javascript and [login to view URL] programs. I need a JavaScript expert to help me Modularize them into small chunks which are simple enough to solved independently. The end goal would be to make everything simple enough to be explained to a student. I would also need some coding practice examples for the same chunks. The language needs to be simple and a flow should be maintained. I would also need some documentation to be prepared for the same. I would hire only after a test activity to see if all my requirements are met. Please bid only if you are well acquainted with javascript and p5.js. Freelancers with prior teaching experience would be preferred.
