TypeScript

Programming language that adds static types to JavaScript, with a compiler (tsc) that converts its code to JavaScript.

TypeScript is a programming language that adds static types to JavaScript. Its compiler, tsc, checks typed code and converts it to JavaScript, which runs wherever JavaScript runs. The compiler is installed per project from npm, and MSBuild projects can use a NuGet package or a Visual Studio extension instead. The npm package starts native binaries built for each platform, and its launcher still needs Node.js. Microsoft Corporation publishes the language and its source in the TypeScript repository.

Worth knowing

The repository’s README says code changes there are limited to a small category of fixes, and most bug fixes for the compiler go to the typescript-go repository.
