QuickJS is a JavaScript engine developed by Fabrice Bellard. In the cited context, scriptc uses it to provide dynamic-mode execution for npm dependencies. Its main documentation is provided in HTML and PDF form in the project repository.

TypeScript is a programming language developed by Microsoft as a superset of JavaScript. It adds optional static types for application-scale JavaScript and compiles to readable, standards-based JavaScript for browsers, hosts, and operating systems. The compiler is distributed through npm, with stable and nightly builds, and the project provides a browser-based playground, documentation, roadmap, and community resources.

Sandpack is a React component toolkit for embedding live-running code editing and preview experiences in web applications. It runs JavaScript and Node.js applications in the browser and can be used for interactive documentation, coding environments, low-code tools, generated website previews, and embedded playgrounds. Sandpack provides templates containing project files and dependencies, custom setup for changing dependencies or file structure, configurable built-in components, themes, and composable components and hooks for custom interfaces. It uses CodeMirror for editor functionality, supports npm dependencies, hot module reloading, error overlays, caching, and Node.js execution through its Nodebox runtime. The Sandpack Client package exposes a framework-agnostic bundler protocol, and the toolkit supports frameworks including Next.js, Remix, Vite, and Astro.

Bun is a fast JavaScript and TypeScript runtime and toolkit created by Jarred Sumner and maintained by the Bun team.
