Announcing TypeScript 3.0

If you’re unfamiliar with TypeScript, it’s not too late to learn about it now! TypeScript is an extension of JavaScript that aims to bring static types to modern JavaScript. The TypeScript compiler reads in TypeScript code, which has things like type declarations and type annotations, and emits clean readable JavaScript with those constructs transformed and removed. That code runs in any ECMAScript runtime like your favorite browsers and Node.js. At its core, this experience means analyzing your code to catch things like bugs and typos before your users run into them; but it brings more than that. Thanks to all that information and analysis TypeScript can provide a better authoring experience, providing code completion and navigation features like Find all References, Go to Definition, and Rename in your favorite editor.
