## What it is
EaselJS is a JavaScript library providing a hierarchical display list, interaction model, and helper classes for building high-performance interactive 2D content on the HTML5 Canvas element. It is part of the CreateJS suite and has no external dependencies.

## Use cases
- draw and animate graphics on html5 canvas
- build 2d browser games with sprite animation
- create generative art in the browser
- make interactive data visualizations with canvas
- handle mouse and touch interactions on canvas shapes
- build animated html5 ads

## When to choose
- you want a Flash-style display list API for canvas
- you need lightweight canvas animation with no dependencies
- you're building 2D games, ads, or visualizations in the browser

## When to avoid
- you need 3D rendering or WebGL shaders
- you want a full modern game engine with physics built in
- you're building DOM-based UIs rather than canvas content

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, graphics, ui-components, game-engine
- domain: web-development, frontend, graphics, data-visualization
- platform: browser
