Dear teachers,

I assume you’re all using processing API in your classroom / coding club. I’d like to ask you: which processing library or environment are you using?

Are you using bare bone [p5.js](https://p5js.org) sketches, processing JavaScript sketches, processing.js library, openprocessing or [codeguppy.com](http://codeguppy.com)?

The beauty of processing is that the skills learns on one platform are transferable to the other … for instance I recently did a conversion of 16 small programs between [Khan Academy](https://khanacademy.org) (based on processing.js) and [codeguppy.com](https://codeguppy.com) (based on p5.js)

If you want to see the results, take a look at this post:

Looking forward to your feedback!
