TypeScript lets you write JavaScript the way you really want to.
TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.
Any browser. Any host. Any OS. Open Source.
Scalable
TypeScript offers classes, modules, and interfaces to help you build robust components.
These features are available at development time for high-confidence application development, but are compiled into simple JavaScript.
TypeScript types let you define interfaces between software components and to gain insight into the behavior of existing JavaScript libraries.
Node.js
