TypeScript is a free and open source programming language. It is a strict syntactical superset of JavaScript and adds optional static typing to the language. As it is a superset of JavaScript, existing JavaScript programs are also valid TypeScript programs. It may be used to develop JavaScript applications for both client-side and server-side execution.
