TypeScript 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, and stay up to date via our blog and Twitter account.
JavaScript and More
TypeScript adds additional syntax to JavaScript to support a tighter integration with your editor. Catch errors early in your editor.
A Result You Can Trust
TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: In a browser, on Node.js or Deno and in your apps.
Safety at Scale
TypeScript understands JavaScript and uses type inference to give you great tooling without additional code.
