JZ (javascript zero) compiles JavaScript to fast, minimal WASM.

site / guide / try it / examples / benchmarks

Good for	Not for
DSP, audio, synthesis	UI, DOM, frontend state
Images, video, pixels	Network, hot I/O, serving HTTP
Simulation, physics, games	Dynamic object models and monkey-patching
Parsers, codecs, compression	Allocation-heavy, long-lived object graphs
Scientific, numeric, edge ML	Security-sensitive cryptography and arbitrary-precision integers
Hashing, checksums, RNG	Tiny calls where the JS/WASM boundary dominates

Usage

npm install jz

import jz from 'jz'
const { exports } = jz`export const square = x => x * x`
exports.square(7) // 49

jz(source, opts) compiles and instantiates. compile(source, opts) returns the wasm, and instantiate(wasm, { imports, memory, wasi })…
