TypeScript is Microsoft's open-source superset of JavaScript, hosted at microsoft/TypeScript, that layers an optional type system onto JavaScript and compiles it down to standards-based JS. The README describes it as built for application-scale JavaScript across any browser, host, or OS. Most day-to-day compiler bug fixes are now directed to the separate typescript-go repository, while this repo gates changes ahead of TypeScript 7.0.

Deno is an open-source runtime for JavaScript, TypeScript, and WebAssembly, maintained in the denoland/deno GitHub repository under the MIT license. Its own quickstart runs a TypeScript file straight through deno run and requires an explicit --allow-net flag before a program can open a network port. The project also points to JSR, an open-source package registry, and the Deno Standard Library as its dependency and utility resources.

Storybook is a frontend workshop maintained at storybookjs/storybook. It renders UI components and pages in isolation from your main application. Core renderers include React, Angular, Vue 3, Web Components, HTML, Ember, Svelte, and Preact, plus React Native and community support for Qwik and SolidJS. It's released under the MIT license.

Awesome React (enaqx/awesome-react) is a curated-list GitHub repository that catalogs frameworks, component libraries, state management tools, styling options, testing tools, and React Native packages for the React ecosystem. It also includes a Real Apps section pointing to production software built with React, plus a Contribution section explaining the project's history and rules.
