the javascript version of processing is called p5js. According to the creator the 5 comes from "the original domain of processing was proce55ing.net, so people used to sometimes refer to processing as proce55ing or P5 or p5 for short. they still do sometimes. p5.js is a reference to that."
Thanks for the answer, although it reinforces my point I think. I remember when Processing was the hot new thing and reading about it was incredibly confusing.
