  "keyword": "TypeScript in practice",
  "summary": "TypeScript adds static typing to JavaScript and acts as an engineering guardrail for large frontends and edge functions. It is a first-class citizen in Astro and Vite, catching most runtime errors at compile time. Three steps: (1) turn on strict:true in tsconfig; (2) use import type to isolate type-only imports; (3) run tsc --noEmit as a CI type gate. Bottom line up front: strict mode is verbose at first, but it stops any debt before merge — the floor for any team. Common pitfalls are turning strict off and accumulating any, and forgetting import type under verbatimModuleSyntax which triggers circular-dependency bundling errors.",
