OpenFrameworks alternative for JavaScript

Question

Recently I've been looking into the field of Visual Regression Testing. I intend to give it a shot developing a tool that compares the visual representation of a site (a screenshot, for example) to the provided design to see if they're a match.

A few years back I had a chance to develop an interactive art installation with OpenFrameworks, which has the capability of proper graphical processing. My question is, though - is there any decent alternative to OpenFrameworks in JavaScript?

Answer 1

openFrameworks now supports Javascript / Browser via Emscripten http://arturocastro.net/files/of-emscripten/

Also, check out p5.js (an updated processing for js) http://hello.p5js.org/
