TypeScript
Starts with JavaScript
All JavaScript code is TypeScript code, simply copy and paste
All JavaScript libraries work with TypeScript
Optional static types, classes, and modules
Enable scalable application development and excellent tooling
Zero cost: Static types completely disappear at run-time
Ends with JavaScript
Compiles to idiomatic JavaScript
Runs in any browser or host, on any OS
