TypeScript is an open source programming language that is a typed superset of JavaScript. It adds optional static typing to JavaScript, which can support tools for large-scale JavaScript applications for any browser, host and OS.
TypeScript compiles to clean, simple JavaScript, and uses existing JavaScript code and libraries. It also offers support for the latest and evolving JavaScript features, such as async functions and decorators.
