p5.js is a JavaScript library that takes the core ideas of Processing and brings them to the web. The first public beta of this open source project has just been released.

Like Processing p5.js has the goal of making coding accessible for artists, designers, educators, and beginners. It provides users with facilities that can be summed up as "Programming for the Arts". In particular, it makes it easy to draw shapes, to add mouse interaction to your drawings and to generate sound.
