TypeScript's Type System
This document discusses type systems and TypeScript. It provides an overview of TypeScript's type system features including gradual typing, structural and generic types, distinct value and type namespaces, extensive type inference, control flow analysis, support for object-oriented and functional programming. It also discusses TypeScript's design goals of being open source, closely tracking the ECMAScript standard, innovating in its type system, having best-in-class tooling, lowering barriers to entry, and focusing on community.
