BFFs TypeScript & JavaScript
summary
TypeScript is a typed superset that compiles to plain JavaScript and adds optional structural typing, interfaces, generics and modules while emitting ES3-compatible output or ES6 when requested. Microsoft teams use it for large codebases — Project Monaco and Visual Studio Online each reach about 150,000 lines — and tools like F12 run TypeScript-compiled code. Tooling includes Visual Studio (Update 2), a browser playground, source maps for real debugger mapping, and definitely-typed for 400+ libraries.
