Processing

Processing is a free, open-source coding language and integrated development environment (IDE) designed to teach programming to students, artists, and designers through visual and interactive projects. Built on Java and created by Ben Fry and Casey Reas, it simplifies syntax and provides built-in graphics capabilities so beginners can focus on creative expression rather than language complexity. Users write sketches that render animations, interactive art, data visualizations, and generative designs. Processing runs on Windows, macOS, and Linux, and has inspired companion platforms like Processing.py and p5.js for Python and JavaScript respectively. The community is active worldwide, with extensive tutorials, a reference library, and forums supporting learners at all levels.
