{"id":27075,"library":"jimpala","title":"Jazzle","description":"Jazzle is an early-stage, zero-dependency ECMAScript transpiler focused on speed and novel technique implementation (e.g., temporal dead zones, super-bound this). Current version is 0.0.0, which indicates a pre-release or initial development phase. It claims ~2x faster than Babel on early benchmarks. Differentiators include zero dependencies, very fast transpilation, and unique support for certain edge cases like temporal dead zones. However, it is not production-ready and lacks CLI, documentation, and maturity. Not recommended for real projects.","status":"abandoned","version":"0.0.0","language":"javascript","source_language":"en","source_url":null,"tags":["javascript","ast","ecmascript","fast","transpilation","compilation","syntax","performance"],"install":[{"cmd":"npm install jimpala","lang":"bash","label":"npm"},{"cmd":"yarn add jimpala","lang":"bash","label":"yarn"},{"cmd":"pnpm add jimpala","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"The package uses CommonJS exports, but if targeting ESM, named import may not work; use default import instead.","symbol":"transform","correct":"import { transform } from 'jazzle'"},{"note":"The package exports a function directly, so default import or assigning require() to a variable is correct.","wrong":"const { transform } = require('jazzle')","symbol":"default","correct":"import jazzle from 'jazzle'"},{"note":"The package uses module.exports = function, so no .default needed.","wrong":"const jazzle = require('jazzle').default","symbol":"require('jazzle')","correct":"const jazzle = require('jazzle')"}],"quickstart":{"code":"const jazzle = require('jazzle');\nconst code = 'let [x] = [1];';\nconst result = jazzle.transform(code, { sourceType: 'module' });\nconsole.log(result.code);","lang":"javascript","description":"Transpile a simple destructuring assignment using the transform API and log the output code."},"warnings":[{"fix":"Use the JavaScript API (transform function) instead of CLI.","message":"CLI is not yet implemented; the README explicitly states CLI is in the making.","severity":"gotcha","affected_versions":">=0.0.0"}],"env_vars":null,"last_verified":"2026-05-01T00:00:00.000Z","next_check":"2026-07-30T00:00:00.000Z","problems":[{"fix":"Run `npm install jazzle` in your project directory.","cause":"The package is not installed or not in node_modules.","error":"Cannot find module 'jazzle'"}],"ecosystem":"npm","meta_description":null,"install_score":null,"install_tag":null,"quickstart_score":null,"quickstart_tag":null}
