" summary

Built a Video Pattern Generator in JavaScript Rust Go compiled to WebAssembly, embedded as a React canvas component and served from Next.js API routes using node canvas to emit PNG streams. Measures: a 720 by 40 frame renders in milliseconds, crossings at 60 fps are fine, Rust edges out JS on one desktop benchmark but JS is often fastest, Go needs a running runtime and larger wasm though tinygo can shrink binaries by about 10x. Lambda instances show per-request dynamic routing.
