From the developer:
p5 is a JavaScript library designed to make coding accessible for artists, designers, educators, and beginners. Using the original metaphor of a software sketchbook, p5.js has a full set of drawing functionality. However, you’re not limited to your drawing canvas. For this, p5.js has add-on libraries that make it easy to interact with other HTML5 objects, including text, input, video, webcam, and sound.
