joy.js is a tiny creative coding library that makes it easy to create 2D shapes, combine them, and apply both simple and more complex transformations.

It started as a p5.js port of the original joy library, which was written in Python.

Over time, I’ve expanded the library by decoupling the rendering engine from its core functionality. This means you can now create multiple renderers, each with its own way of handling shapes and transformations, while still using the same concise and powerful API.
