microsoft/vscode is the GitHub repository where Microsoft develops the Visual Studio Code editor together with the community, published under the MIT license. The README draws a clear line between this open Code - OSS source and the Microsoft-branded Visual Studio Code product, a separate distribution built from this code plus Microsoft-specific customizations.

Electron (electron/electron on GitHub) is an open-source, MIT-licensed framework for building cross-platform desktop apps with JavaScript, HTML, and CSS on top of Node.js and Chromium. The README covers installing it as a dev dependency through npm, lists platform support for macOS, Windows, and Linux, and points to a companion tool, Electron Fiddle, for trying the API before starting a full project.

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.
