Elite JavaScript

Zero-dependency browser experiments. WebAssembly edge. Service Worker mastery.

JavaScript that treats the browser as a systems platform. No bundlers, no frameworks, just vanilla JS + Web APIs pushing WebAssembly, SharedArrayBuffer, and OffscreenCanvas to their limits.

Flagship Experiments

Pithy Neural Kernel

A browser-native neural playground with a systems feel. Weird, kinetic, and very online in the best way.

• Demo:pithy-neural-kernel
• Code:GitHub source

Pithy VerLite

A zero-dependency cloth physics experiment with marbles, tearing, pressure, and just enough chaos to keep it fun.

• Demo:pithy-verlite
• Code:GitHub source

More Experiments

Experiment	Bundle Size	Key Technique
No-Alloc Parser	2.1KB	TextDecoder → AST, zero GC pressure
Lock-Free Queue	1.8KB	SharedArrayBuffer + Atomics
WASM SIMD	3.4KB	WebAssembly SIMD + postMessage zero-copy
Terminal Renderer	4.2KB	OffscreenCanvas + 60fps block graphics

Characteristics

• No bundlers: Single index.html files, <script> tags only
• No frameworks: Vanilla JS + Web APIs exclusively
• Bundle ≤ 5KB: Gzip targets for instant loading
• Service Workers: Offline-first, cache-first architecture
• Complete demos: Open index.html and it works immediately

Philosophy

JavaScript's strength is WebAssembly integration. These experiments show how to:

1. Build WASM allocators without Emscripten
2. Run 60fps terminals via OffscreenCanvas
3. Build lock-free data structures with Atomics
4. Create zero-copy pipelines via ReadableStream

Usage

git clone https://github.com/pithycyborg/elite-javascript
