TypeScript is an open-source programming language developed and maintained by Microsoft. It’s a strict syntactical superset of JavaScript, and adds optional static typing to the language. Use existing JavaScript code, incorporate popular JavaScript libraries, and call TypeScript code from JavaScript.
TypeScript compiles to plain JavaScript code which runs on any browser, in Node.js, or in any JavaScript engine that supports ECMAScript 3 (or newer).
TypeScript offers support for the latest JavaScript features, including those from ECMAScript 2015 and future proposals, like async functions and decorators, to help build robust components.
TypeScript is published under the Apache License 2.0.
