## What it is
regl is a fast functional WebGL library for JavaScript that replaces the raw WebGL API with declarative resources and commands. It compiles state descriptions into optimized draw calls, removing shared mutable state from GPU programming.

## Use cases
- render 2D and 3D graphics in the browser with WebGL
- write declarative GPU draw commands without managing WebGL state
- build data visualizations that need high-performance rendering
- create shader-based animations and generative art
- prototype graphics demos quickly in JavaScript
- draw thousands of objects efficiently with batched WebGL commands

## When to choose
- you want a functional, stateless abstraction over raw WebGL
- you need high-performance rendering for visualizations or demos
- you prefer declaring draw state once and reusing compiled commands
- you want a lightweight library rather than a full 3D engine

## When to avoid
- you need a full scene graph, cameras, and asset loading out of the box
- you are targeting WebGPU instead of WebGL
- you want a batteries-included game engine with physics and lighting
- you need React-style component integration without writing wrappers
