TypeScript: Why? When? How?
summary
Presents TypeScript’s benefits and adoption: it catches roughly 10–15% more bugs at compile time, integrates with IDEs via a language service (e.g., VS Code), and has reached large-scale use (~1 million daily downloads). Covers practical tooling and techniques: tsc, tsconfig and tslib for downleveling and shared helpers, .d.ts and DefinitelyTyped/@types for using JS libraries, experimental decorators, strict mode for safer typing, and a non‑invasive migration path using --checkJs plus JSDoc.
