## What it is
Processing.js is a JavaScript port of the Processing visualization language, allowing Processing sketches to run in the browser via HTML5 canvas. The project was archived in December 2018 in favor of p5.js.

## Use cases
- run Processing sketches in the browser
- creative coding with canvas graphics
- port Java Processing code to JavaScript
- teach programming with visual feedback
- build interactive data visualizations

## When to choose
- you must run legacy Processing.js sketches
- you need compatibility with old Processing.js-based code

## When to avoid
- starting a new creative coding project - use p5.js instead
- you need modern Processing API features
- you need maintained software with active support

## Facets
- artifact type: library
- maturity: abandoned
- function: graphics, animation, data-visualization, interpreter
- domain: graphics, web-development, data-visualization
- platform: browser
- tags: processing-language, creative-coding, canvas, archived-project, visualization-language, game-development, javascript
