Introduction to TypeScript
summary
A practical tour of TypeScript: a typed superset of JavaScript that compiles to plain JS, adds optional static types plus classes and modules, and runs on Node, browsers or any JS host. Demos use the TypeScript playground and Visual Studio, show DOM and jQuery typings, a small Battleship app, and the DefinitelyTyped repo (~180 libraries, ~100 contributors). The compiler (written in TypeScript) emits CommonJS or AMD, scales to 100k+ lines, and prepares generics in 0.9 while keeping TypeScript compiler outputs standard JavaScript.
