-# TypeScript (Native Preview)
-
-This package provides a preview build of [the native port of TypeScript](https://devblogs.microsoft.com/typescript/typescript-native-port/).
-Not all features are implemented yet.
-
-This package is intended for testing and experimentation.
-It will eventually be replaced by the official TypeScript package.
-
-## Usage
-
-For TypeScript 7.0 RC and later, use `tsc` just like for TypeScript 6.0.
-
-For other builds, use the `tsgo` command just like you would use `tsc`:
-
-```sh
-npx tsgo --help
-```
-
-The JavaScript API requires Node.js 20.16 or later when it starts the compiler itself. In other environments, provide a transport.
-
-## Issues and Feedback
-
-The native port of TypeScript is still in progress.
-We expect many gaps, but are seeking experimentation and feedback.
-If you have found differences that are not yet known, we encourage you to leave feedback on [the issue tracker](https://github.com/microsoft/TypeScript/tsc/issues).

-[TypeScript](https://www.typescriptlang.org/) is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the [playground](https://www.typescriptlang.org/play/), and stay up to date via [our blog](https://devblogs.microsoft.com/typescript/) and [Bluesky](https://bsky.app/profile/typescriptlang.org).
