Opening Remarks
summary
History and claims condense to measurable facts: TypeScript ships in October 2012, moves to GitHub and open development, adds decorators then drives Angular adoption, and powers Visual Studio Code. The language service (TS server) enables editor features, DefinitelyTyped grows to 42,000 commits 6,000 committers, and npm usage hits 10 million monthly downloads. Conditional types arrive in 2.8 and add new utility types. Restructuring into composite projects yields real speedups — 2m8s → 30s → 14s on the compiler build.
