Updates have been trickling in over the last few releases, and while the original dev team for Processing.js moved on, there are a number of enthusiastic users who have been finding problems with the library and have been willing to help fix them. As such, the current version has quite a few improvements compared to the version of Processing.js you might find bundled with some processing bundles, but: if there are things it doesn't do that you rely on, do head over to the Processing.js issue tracker and let people know.
We're also happy to get help in the form of pull requests to add functionality to Pjs, or to simply fix small errors that were found. You don't have to be a code wizard to contribute: if you simply know of a function or a constant that's missing, feel free to fork the code, patch what you think needs patching, and file a Pull Request so that we can merge your improvement in! Don't know where to start? Drop into our IRC channel, #processingjs on irc.mozilla.org, and we'll be happy to help you get the most out improving Processing.js!
Processing.js is a project based on the popular Processing visual programming language, designed to bring Processing sketches to the web without a need for special browser plugins. Processing.js makes your data visualizations, digital art, interactive animations, educational graphs, video games, etc. work using web standards and without any plug-ins. You write code using the Processing language, include it in your web page, and Processing.js does the rest. It's not magic, but it's close.
Originally developed by Ben Fry and Casey Reas, Processing started as an open source programming language based on Java to help the electronic arts and visual design communities learn the basics of computer programming in a visual context. Processing.js takes this to the next level, allowing Processing code to be run by any HTML5 compatible browser, including current versions of Firefox, Safari, Chrome, Opera, and Internet Explorer. Processing.js brings the best of visual programming to the web, both for Processing and web developers.
Whether you're an advanced Processing developer or completely new, whether you're a pro with web technologies or just getting started, Processing.js bridges the gap between these two powerful technologies.
